Diamond Clarity Color Chart

DIAMOND CLARITY COLOR CHART

Clarity and Color are two of the four characteristics (4 c’s) used in determining a diamond’s value. So let’s have a look at a diamond clarity color chart and find out how these characteristics are graded.

Round brilliant diamond

A Diamond’s Cut is the most important characteristic in a diamond and now we will view the other three characteristics, Color, Clarity, and Carat weight.

 

 


DIAMOND | COLOR 

The Color of a diamond is the second most important characteristic influencing value.
Color rates second because it is the second feature we naturally see after experiencing the brilliance, fire, and scintillation displayed by an excellent or ideal cut.

There are a variety of colors within the structure of a diamond stone which includes whites, pinks, blues, and yellows.
Yellows have a lower value, with an exception, while a white diamond will reflect more light and color, and be more valuable.
As a general rule the less color in a diamond the higher the value. Grading is based on a lack of color and scales down from the highest D grade to a yellow Z.
D grade color diamonds are extremely rare and expensive, and if you are on a budget and after an almost colorless diamond, G grade offers exceptional value.

The exception mentioned above relates to a particular canary yellow colored diamond that has single nitrogen atoms. These diamonds are exquisite and extremely expensive as are the blues, reds and pinks.

DIAMOND | CLARITY 

Clarity is the third most important characteristic in a diamond and refers to the size and number of imperfections present in a stone.

Almost all diamonds have one or more imperfections. Diamonds without a flaw are very rare and expensive.

Diamonds form deep in the Earth’s mantle under extreme heat and pressure and deposit onto Earth’s surface through the violent action of volcanic eruptions. As a result, almost all diamonds have some sort of imperfection(s), commonly referred to as birthmarks. Internal flaws are called inclusions, external or surface are called blemishes.

Clarity determines value because it can affect light travelling through the diamond. Larger and more numerous imperfections have less brilliance because light does not refract as well as stones having fewer flaws.

Diamond clarity grading scale

 

FL – Flawless / no visible inclusions or blemishes under 10x magnification, <1{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff} of diamonds.
IF Internally Flawless / Very slight blemishes under 10x magnification, <3{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff} of diamonds.

VVS1 – Very, Very Slightly Included / few microscopic flaws very difficult to view under 10x magnification.
VVS2Very, Very Slightly Included / Slightly more tiny imperfections difficult to view under 10x magnification.

VS1 Very Slightly Included / minor inclusions somewhat difficult to see under 10x magnification and located to the outer rim of the diamond.
VS2Very Slightly Included / minor inclusions the same size as VS1 but located more towards the centre and sometimes within the table. Inclusions towards the girdle will be a bit larger in size or formation than a VS1.

SI1 – Slightly Included / inclusions that are fairly easy to see with 10x magnification but not quite visible without a loupe.
SI2Slightly Included /the most common diamond clarity on the market. Properly graded the SI2 clarity diamond still requires magnification to identify any inclusions. Inclusions can be anywhere in the stone, from the table to the girdle. However, you should not be able to see any inclusions with the unaided eye.

Other categories – (not recommended) 

I1 – Included / flaws that are obvious under 10x magnification and visible to the unaided eye but do not impact on the strength or beauty of the stone.

I2 – Included /Inclusions either affect the durability of the diamond or the beauty.

I3 – Included /Inclusions that affect both the durability and beauty of the stone.



Enhanced Color and Clarity Treatments

There are other methods used to enhance a diamond’s appearance. Methods that should be disclosed to the buyer before purchase. You will notice I said the word should. By law, you have to be informed but that is not always the case as mentioned above regarding rogue dealers and some online auction sales. Treatment can synthetically enhance diamond clarity and color. Irradiated diamonds, for example, are genuine diamonds that have been exposed to active radiation to enhance color. These crystals display strong colors such as green, black, pink, blue, etc.! If you know what to look for and have the right tools you can identify irradiated diamonds. But please stay away from Irradiated Diamonds, they are Dangerous and we want to sparkle not glow!!! I am sure you wouldn’t see Superman flying through the air wearing a kryptonite ring.
Other diamond enhancement treatments include color coating, fracture filling, laser drilling and exposure to high-pressure high-temperature processes.


DIAMOND | CARATS 

 

Round brilliant diamond

 

The last characteristic you need to consider when selecting the diamond of your choice is the weight.
The unit of weight measurement for a diamond is a Carat (ct).
A Carat weighs 0.2 g, (200 mg), or the equivalent to 0.00705479 of an ounce.

For example, a diamond weighing 90 mg is 0.45 ct  (90 ÷ 200 = .45).

It is rare to find a rough stone large enough to produce a one carat diamond. Larger diamonds are extremely rare and dramatically increase in price. For example, a three-carat stone will be more than three times the price times compared to one carat.

All 4’C’s determine the quality and value of a diamond with the cut clearly the winner. From excellent cuts to poor cuts, the differences in color, the number and size of imperfections, all having an effect on the stone’s price.


Summary

  • If purchasing a ring select a shape that best suits the physical features of the person who will wear the ring. Consider hand, finger, size, length and shape.
  • Not all patterns are suitable for every finger and hand.
  • Choose the ideal cut. I would much rather buy a smaller excellent cut diamond than a large poor cut diamond. You do want the sparkle – right?
  • Identifying any color in G – H coloured diamonds is tough. They are less expensive than rare colourless stones and offer great value.
    I – J are near colorless and have just a very slight tone of warmth about them. They are also a good choice for value.
  • SI quality diamonds are the less expensive in clarity value and have only slight inclusions visible without magnification.
  • Weight will depend on budget and the characteristics you have selected.
  • Small heart shaped diamonds under 0.50 carat have little definition. The heart shape is lost in the stone and is not well recognised. You may wish to choose a round brilliant stone.

A diamond ring will most likely be worn for a lifetime so you want that scintillating captivating sparkle day after day. Choose quality before size. You don’t want to make a decision you will regret later on in life! and if you wish to view my advice please click my review and recommendations, it could save you thousands.

Identify Real Diamond

IDENTIFY REAL DIAMOND

The most common question asked when buying buy a diamond is “How do you Identify Real diamond? Can you tell if the diamond is real?
Diamonds are costly, and you want to make sure you have the real McCoy, RIGHT? So ask yourself this question, do you honestly know the difference between real diamonds vs fake diamonds?

If you can identify real diamond, there’s no fooling you! But if you can’t, which not many people can, I just hope you avoid crossing paths with a rogue dealer ready to rip you off with a fake (faux) or an underweight stone. And yes you should be careful because they are out there ready to pounce.

Let’s say, for instance, we have a diamond stone set in a ring and valued at $10,000 a carat. It is selling as a one carat stone, and it appears the size of one carat, but in fact, it is only 0.87 carat because it is a shallow cut not visible due to the fact it is set in the ring. The real value should be $8,700.00, but the consumer is paying $10,000.00 and cheated 0.13 of a carat equating to a shortfall of $1,300.00. Do you know how to tell if this diamond is underweight? I am pretty sure not many people could tell. And can you recognise faux which is a stone that looks like a real diamond but made from a different material? When a faux is extremely well-made the only way, we can identify it’s authenticity is to test it. Cubic zirconia and moissanite are the most famous of all the fakes.

ONLINE
To avoid being stung by unscrupulous dealers, I recommend the reputable online dealers who are noted for credibility and offer a 100{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff} guarantee. You need PROTECTION!!!.
In my opinion, this is a better and more secure option if you are not sure about diamond quality and authenticity unless you have a real association and relationship with a dealer, you can trust.

METHODS USED TO IDENTIFY REAL DIAMOND

The Fog Test:
Breathe on a clean stone and make it fog. If it’s a real diamond, the fog will disperse immediately. If it is fake, the fog will stay for a couple of seconds and if you repeatedly breathe on a fake, you will see condensation accumulate. The real diamond is a good heat conductor and you can use a fake for comparison if you have one handy.

Check the Transparency:
If it’s a loose stone (unmounted), turn it upside down on printed paper and try to see through it. On viewing, if the letters are visible; it is most likely fake. If the letters are not visible, then there’s a good chance it’s a genuine diamond.

Check the mount:
It is most unlikely you will find a real diamond set in a cheap material. Check the setting for the gold, platinum or silver identification stamp.
CZ stands for cubic zirconia which is an imitation.
Gold: 9K – 10K – 14K – 18K.
Look for any discoloration which could signal it is gold plated.
Platinum: 850 (85{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff}) – 900 (90{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff}) – 950 (95{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff}) – 999 (99.9{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff}).
Silver: S925 (92.5{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff}) sterling silver – 999 pure silver.
Gold is magnetic, platinum and silver are not magnetic.
Use an acid testing kit: This can mark jewellery, so it is best to use it on a section of the jewellery that cannot be seen.

Cubic zirconia

Hydrogen Peroxide:
Fill a glass with hydrogen peroxide, drop the jewellery into the glass making sure the jewellery is fully submerged, then wait for a reaction. Platinum is an active catalyst for hydrogen peroxide and will bubble immediately. Silver is a weaker catalyst and requires a longer time to see a response which can take up to a minute for small bubbles to develop.
This method will not corrode or damage your jewellery.

Loupe:
All diamonds contain imperfections within their structure (inclusions) or on their surface (blemishes). Inclusions are the birthmark of the stone, and visible under a loupe. A loupe is a 10x jeweller’s magnifying glass and can pick out the perfection of cubic zirconia and moissanite rings. The scale to which these imperfections are present is the diamond’s clarity. Using loupe magnification can help identify a moissanite. If you view a diamond through one of its bezel or star facets on the crown and it appears to have two of each facet line then it is most likely a moissanite.
Natural diamond will only display one of each facet line, as will cubic zirconia (CZ). Magnification is required to identify the difference between real diamond from a CZ. The girdle of a real diamond will have a grainy or frosted appearance whereas a CZ will be totally smooth. The girdle of diamond is the narrow edge around its circumference.

Heat Test:
Beware, this will most likely destroy your jewellery if it’s fake but will not break a diamond due to its incredible strength. This test involves heating a loose stone over a naked flame for about 30 seconds and then dropping it straight into a bowl of cold water. A fake diamond will most likely crack or shatter from the inside whereas a real stone will not react at all.

Diamond Tester:
Diamond testers identify diamonds from all other stones except moissanite. Gemstones have different rates of thermal conduction; however, diamonds and moissanite are both very efficient in conducting heat and need to be tested individually for identification. To be sure we have a real diamond we need to perform a moissanite test on the stone.

 

Let’s work out the best solution to be sure we have a real diamond

  1. We have used the diamond tester and identified it is possibly a diamond or it is not a diamond.
  2. If the test shows up a diamond, then it is either a diamond or moissanite.
  3. Next – verify the stone on a moissanite tester, if it tests moissanite, then you have a diamond. Moissanite testers measure electrical conductivity. Diamonds do not have free electrons and are poor electrical conductors, whereas moissanite is electrically conductive.

Please note: there is a rare form of diamond that has a chemical composition comprising boron atoms making it electrically conductive. It will test as moissanite on the moissanite tester. These diamonds are rare and total less than 0.001{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff} of diamonds.

 



Enhanced Diamonds – RADIATION

There are other methods used to enhance a diamond’s appearance. Methods that should be disclosed to the buyer before purchase. You will notice I said the word should. By law, you have to be informed but that is not always the case as mentioned above regarding rogue dealers and some online auction sales. Treatment can synthetically enhance diamond clarity and colour. Irradiated diamonds, for example, are genuine diamonds that have been exposed to active radiation to enhance colour. These crystals display strong colours such as green, black, pink, blue, etc.! If you know what to look for and have the right tools you can identify irradiated diamonds. Please stay away from IRRADIATED DIAMONDS, they can be DANGEROUS and we want to sparkle not glow!!! I am sure you wouldn’t see Superman flying through the air with a kryptonite ring on his finger.
Other diamond enhancement treatments include colour coating, fracture filling, laser drilling and exposure to high-pressure high-temperature processes.

It may well save you thousands and the peace of mind knowing that the advertised described stone you wish to purchase is the one you’ll receive. Diamonds are supposed to be forever and worn for a lifetime. It would be a great disappointment if you found out years down the track that your stone is a fake, or underweight, or enhanced in any way if you did not previously know on the original purchase.

If you have a suggestion for identifying real diamonds, please leave a comment as your comment may also help others.

What is a Diamond Stone?

What is a Diamond Stone? 

Remember the famous 1949 song made famous by the late and great Marilyn Monroe, “Diamonds are a Girl’s Best Friend.” The association between her and a Diamond showcasing the glamour, the beauty, the sparkle, the elegance, and the fame. But why is this Diamond stone so famous and posses the power to have the entire world under her spell? What is she made of? What is a Diamond stone?

A Diamond Stone is a crystalline mineral made of carbon and forms in a cubic crystal system

Diamonds contain many covalent bonds with each carbon atom chemically bonding to four other carbon atoms in a triangular pyramid (tetrahedron). This makes a Diamond so incredibly strong. A Diamond’s extremely high melting point >3500 °C / 6332 °F is the result of covalent bonding.

Diamond is technically an allotrope of carbon and is the hardest naturally occurring material found on the planet.
Graphite is also an allotrope of carbon but has a different bonding arrangement between atoms.

                    G) AMORPHOUS CARBON

                    H) SINGLE – WALLED CARBON NANOTUBE


Diamond Hardness

Diamonds are the hardest natural substance on our planet. However, this doesn’t mean they won’t break because hardness is only a measurement to identify a mineral’s resistance to scratching.

In 1812 the Mohs Scale of Mineral Hardness was created by a Geman geologist by the name of Friedrich Mohs. Mohs compared the hardness of minerals and the ability of one mineral to visibly scratch another.

The Mohs Scale of Mineral Hardness comprises ten minerals with talc being the softest and Diamond the hardest. The Mohs Scale only goes to (10), so please bear in mind that Diamonds are far harder than their nearest rival which is corundum at (9). However to give you a better perception of how hard a Diamond really is, if it the scale went to 40 then a Diamond would be 40 and its next nearest rival corundum remaining at 9.

 

The order of the Mohs Scale from softest to hardest:

  • (1) Talc
  • (2) Gypsum
  • (3) Calcite
  • (4) Fluorite
  • (5) Apatite
  • (6) Orthoclase
  • (7) Quartz
  • (8) Topaz
  • (9) Corundum
  • (10) Diamond

 

 


Violent Volcanic Eruptions

Diamonds deposit on the Earth’s surface as a result of deep-sourced volcanic eruptions pushing Magma (molten rock) upwards through volcanic pipes (kimberlite and lamproite). These violent volcanic eruptions occur at depths twice as deep as your average volcano and originate approximately 150 km or 90 miles down in the Earth’s mantle. Diamond travels at speeds exceeding 800 km an hour, along with other volatile compounds, and deposit onto the surface of the Earth within a magmatic rock called kimberlite.

A Diamond is a xenocryst which is a crystal inclusion within an igneous rock.

Kimberlite volcanic pipe
Kimberlite volcanic pipe

Diamond formation requires the presence of extreme heat >1400 °C / 2552 °F, and an enormous amount of pressure exceeding speeds of 800 km an hour (500 mph) through volcanic pipes to reach the Earth’s surface. The speed of the upwards propulsion is what determines whether it is Diamond or graphite.


Finding Diamond 

Kimberlite ore (magmatic rock), deposits in depths of at least 15 m, or 49 ft underground, from the result of these violent volcanic eruptions and the only way to remove the ore, is by digging.

So when it comes to mining for deposits of commercially useful Diamonds, near the Earth’s surface, Open-Cut Mining is the preferred method of extraction.

Natural and artificial features of a geographical area determine the size and shape of an open cut mine. Some of these features include the physical structure and substance of the earth, the grade (cut-off), the extent of deposits, property boundaries, bench height, road grades, the slope of the pits, and mining and processing costs.

UNDERGROUND MINING

Another method used to extract Diamond from the Earth is underground mining.

Underground mining can be accessed in three ways:

Decline – A type of ramp that spirals around the deposit.

A decline underground mine

Vertical Shaft – A vertical excavation adjoining a body of ore.

Vertical Mine Shaft

AditHorizontal excavations used for bodies of ore that are horizontal or near-horizontal.

Adit mine

Horizontal levels are dug out off the decline or shaft to gain access to the body of ore. A series of steps or layers (stopes) are excavated into the rock at an angle of 90°, or thereabouts, to the level into the ore. This action is known as stoping, a process of extraction where cavities known as stopes are left behind in the underground mine.


TOP TEN DIAMOND MINES IN THE WORLD

Jubilee – the biggest Diamond mine in the world – Russia (Yakutia region)

Udachny – one of the deepest open pits (630m) – Russia (Yakutia region)

Argyle – Australia (Western Australia)

Mirny – Russia (Yakutia region)

Catoca  Angola

Venetia – Limpopo province of South Africa

Grib – Russia (Arkhangelsk region)

Jwaneng – considered the richest mine in terms of value -Botswana

Orapa – Botswana

Botuobinskaya – Russia (Yakutia region)


ALLUVIAL MINING

Alluvial Diamond deposits emerge from the natural processes of erosion and weathering of kimberlite over millions of years. These deposits end up in river beds, under the ocean or on shorelines.

Twelve miles off Namibia’s southern coastline and 150 metres below the sea, Diamond miners are working to secure their future. The large Diamond company (De Beers) is building up a naval fleet in a joint operation with the Namibian government to protect its future and interests. De Beers estimates that 95{049d3018651de2a7e433ffb13acdc36a21b9ea4fa995a70edf1ffcc6a2970dff} of its Diamonds will eventually be sourced from the seabed off Africa’s south-west coast in the future.

Below is a picture of the DeBeers ship Peace in Africa the largest remote-controlled deep-sea dredge in the world.

Australian Black Opal Stone

The Lightning Ridge Black Opal

Australian Black Opal Stone – The Birth of Black Opal

The birth of Australian Black Opal Stone began around 600 to 500 million years ago when the suturing of the ancient continent Gondwana evolved.

Gondwana was an incredibly massive continent incorporating many land masses that are now part of our Southern Hemisphere. Lands forming this ancient continent included the Indian subcontinent, the Arabian Peninsula, South America, Africa, Madagascar, Antartica, and Australia.

In the ancient times of Gondwana, an inland sea producing significant amounts of silica-laden sediment covered the central part of today’s Australian continent. The presence of this inland sea provides the seed for the birth of Opal by depositing vast quantities of Silica into small cracks in rocks (voids), decomposed fossils, and in layers of clay. In summary, Black Opal is the result of water flowing down through the earth and picking up silica from sandstone on the way. The water evaporates and the silica-rich deposits are left behind creating a path for the birth of opal.

Silica naturally nourishes our marine environment and the many marine fossils, fish bones, and shells found in central Australia confirm the existence of this Silica bearing inland sea.


Australian Black Opal Stone – The Legend

Sanskrit is an ancient language in Hinduism, and there is the belief that the English word Opal, evolves from the Sanskrit word upala, meaning ‘valuable or precious stone.’

The name Opal may also be associated with the Greek word opallios, meaning ‘to see a change in colour’. The ancient Greeks also believed Opals (opallios) to be the ‘Tears of Zeus.’

The ancient Australian Aborigines believed the opal to be half serpent and half devil. The beauty of the fire colours within the stone would lure and trick someone to enter the demon’s den.

Today, the Aboriginal legend tells the birth of opal happening when the footprint of the creator touched the earth at the base of a rainbow to bring harmony.


Australian Black Opal Stone – Wallangulla (LR)

The Australian black opal

Black Opal stone is native to Australia. It is unique and rare. And you can only find this precious gemstone in Lightning Ridge and the surrounding Opal fields of the Wallangulla region in outback NSW, Australia.

Located approximately 730 km north-west of Sydney and 730 km south-west of Brisbane, Lightning Ridge (LR) has no traffic lights and is home to the Black Opal.

Lightning Ridge is the only place in the World where black opal is commercially produced and for more information on opal mining in Lightning Ridge please visit Lightning Ridge opal mining.


Australian Black Opal Stone – What is Black Opal?

The Australian Black Opal Stone is a non-crystalline natural gemstone that most often changes colour when rotated at different angles.

This rare and unique gemstone is a formation from the combination of silicon dioxide (silica & oxygen) with water, and ideally between 3 to 10 percent moisture content by weight. Quality solid Black Opal Stone contains 5-6 percent water.

The estimation for a 1 cm thick silica vein to form is around 5-6 million years.

For more information please click on this link → What is Black Opal?


Australian Black Opal Stone – Seams & Nobbies

The Australian Black Opal is a highly valued gemstone and can attract a price of up to US $15,000 a carat.

Black Opal Stone exists in claystone layers at depths between 20 to 60 feet below the ground surface of the Griman Creek Formation and the greyish claystone (opal dirt) lies below overlying sandstone and conglomerate rock.

Black Opal forms in horizontal deposits referred to as seams and also forms in rounded nodules of potch and colour called ‘nobbies.’

Mining Black Opal is hard yakka and the best time to prospect is in the colder months due to the extreme hot conditions during summer.

And in the earlier days, picks and shovels were the only tools available to remove rock.


Australian Black Opal Stone – Body & Soul

australian black opal stone
Transforming rough into a small cab

When an opal is cut, rubbed, shaped, and polished into a finished gemstone, it is called a cabochon. The cabochon is then made into beautiful jewelry such as pendants, bracelets, rings, and earrings. However, in some circumstances, it is best to go with the shape of the opal and not to try and do a fancy cabochon, WHY? because you can lose colour. I have been there and done that. If you do happen to have a piece that you can get a nice cab out of, then go for it. But, if youdon’t just go with the flow and shape of the stone, and retain as much colour as you possibly can. Colour is opal.

Identifying loose Solid Black Opal is easy because there are no layers. However, imitation Black Opal set in jewelry can be more difficult to recognize, and by Australian law, must be labeled as imitations. The most common known imitations are the Gilson opal (laboratory-produced), doublets, and triplets. Price should also be a guide in determining whether the opal is a solid black opal or an imitation!!! It should also be noted that Ethiopian opal is not black opal.

ALL Opals n Jewels Australian Solid Black Opals DO NOT have any materials adhered to their structure and are unaltered natural pieces of art more scarce than diamonds. We do not sell doublets, triplets or synthetic Opal. ALL Opals n Jewels opals are solid Australian Black Opal Stone.


Australian Black Opal Stone – Opal Facts

  • Australia produces approximately 95 percent of the World’s Opal
  • South Australia provides about 80 percent in the form of White Opal
  • Queensland and NSW share the remaining 15 percent
  • Queensland is known for Boulder Opal
  • The NSW town of White Cliffs is famous for the Pineapple and White Opals
  • The NSW town of Lightning Ridge is World renowned for the rare Black Opal

Australian Black Opal Stone – Australian Opal Guide

There are rogue dealers in any industry, and the jewelry industry is no exception. There are those that will falsely advertise fakes as the real deal. So if a merchant presents you with an opal, set in jewelry for under $30, the chances are it’s an imitation.

What to look out for:

  • The Country of Origin – 95 percent of the world’s opals come from Australia
  • Price – The rare Australian Black Opal is not cheap, and can attract a price of up to Aud $20,000 per carat
  • Patterns – laboratory made stones have snake-like orderly patterns.
  • Colours – large bright patches indicate an artificial opal.
  • The Depth of Colour – Colour just beneath the surface indicates a fake, depth of colour indicates a real opal (view under white light only).
  • Layers – check the sides to see if there are any layers.
  • Cloudy Stone – If you see a cloudy stone then it is most likely a doublet or a triplet (water penetrating through an adhered layer).

It would be great to hear your thoughts on Black Opal, and if you have any questions, please feel free to ask.

We have a stunning collection of beautiful solid Black Opal stone pendants and necklaces for you to choose from.

By the way, if you like opal what is your favourite colour?
