How to identify a fake diamond?
Diamonds are difficult to replicate due to their very particular qualities, however it does happen, and some copies are very convincing.
zircon
At first glance, the Diamond is difficult to distinguish from the Zirconia , since they are very similar in shape. However, a skilled gem jeweler will be able to do it. For example, with the magnifying glass , zircons have a great dispersion of light, which you can appreciate when looking at the stone from the crown, if you look at it through the "pavilion" you will see an orange-brown glow over this area. This phenomenon is not observed on diamonds.
Every gemologist and expert has the tools to prove the authenticity of stones. A simple apparatus that tests the conductivity of heat will do. The difficulty, however, is distinguishing a true diamond from a synthetic diamond , a much more technical issue.
The magnifying glass is another fundamental tool to study diamonds well. The magnifying glass allows you to see the inclusions, that is, the defects and irregularities of the stone, and also identifies if the facets of the stone are scratched or damaged. To identify a fake diamond, its purity is taken into account. It is very rare to find 100% pure diamonds, if the magnifying glass does not find inclusions, it is probably a synthetic or fake diamond.
real diamond
Another widely used tool is the precision balance that reveals the weight of the stones. This means that stones of the same size can have different weights. A diamond weighs less than another imitation or a zircon, at the same size.
And another way to verify it is with an optical reflectometer , which determines the refractive index of the stone. As the natural diamond has a very high refractive index (IR), the highest of all precious stones (between 2,407 and 2,451, depending on the wavelength of the light), the measurement of this refraction will be decisive to know if your diamond is authentic.
Tips and some tricks to identify a fake diamond
Due to the rarity of genuine diamonds and the price per carat of natural diamonds, many try to pass off synthetic diamonds as genuine diamonds. To distinguish them, there are some tricks that can help:
Draw a black line on a blank paper, and put the stone on the paper. If the well-defined line is distinguished, it is undoubtedly a false diamond. Indeed, the synthetic diamond, or the zirconia, allow to see it.
If a small drop of water is placed on the surface of the diamond well cleaned of grease and it is moved with a needle, the water retains its globular shape, on top of a zirconia, the water spreads over the surface.
By placing a diamond in a glass of water, it is perfectly observed and shines through the liquid, while the zirconia becomes almost transparent and difficult to locate.
In any case, when in doubt, the best choice is to consult with an expert jeweler in gems.
