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.
To avoid being stung by unscrupulous dealers, I recommend the reputable online dealers who are noted for credibility and offer a 100% 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%) – 900 (90%) – 950 (95%) – 999 (99.9%).
Silver: S925 (92.5%) 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.

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.
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.
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 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
- We have used the diamond tester and identified it is possibly a diamond or it is not a diamond.
- If the test shows up a diamond, then it is either a diamond or moissanite.
- 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% 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.
