Diamond imitations and authenticity in the market

Imitation diamonds are not diamonds. Since diamond imitations have a dazzling appearance similar to that of real diamonds, and are relatively cheap, consumers can keep up to date with the latest jewelry fashions with less money. But no matter how similar the appearance is to a real diamond, professional gemologists can identify the different optical and physical properties of a diamond imitation and a real diamond.

How does the gia diamond certificate help you identify natural diamonds?

Gia tests each gem tested to determine whether it is a true diamond. Gia will not issue certificates for diamond imitations.

Synthetic diamonds Synthetic diamonds are synthetic diamonds produced by scientific methods, not natural diamonds formed during geological changes. Synthetic diamonds and natural diamonds do not differ in chemical composition, crystal structure, optical properties and physical properties. Most synthetic diamonds can be classified as hpht (high-temperature high-pressure) diamonds or cvd (chemical vapor deposition) diamonds depending on their synthesis technology. Hpht diamonds and cvd diamonds are almost exactly the same as natural diamonds. Their differences in atomic structure levels can only be identified by a professional appraiser in a gemological laboratory.

Although the proportion of synthetic diamonds in the current jewelry market is very low, its development trend cannot be ignored, and it is increasingly difficult to identify synthetic diamonds. Gia has always been at the forefront of this challenging area, offering synthetic diamonds with different certifications than natural diamonds to avoid misleading consumers.

How to distinguish carbon silica and diamonds?

Synthetic carbon silica is a simulated diamond. There is a big difference between quality and real diamond. Only a veteran gemmologist can distinguish between the two, so if you have questions, send the diamond to a qualified independent laboratory for identification.

Precautions for Purchase Natural high-quality diamonds are rare and expensive, so people have been researching ways to optimize or reproduce diamonds. In recent years, various processed diamonds, imitation diamonds, and laboratory-cultivated diamonds (synthetic diamonds) have become increasingly rampant and the craftsmanship has become more sophisticated and difficult to identify.

Manual processing can increase the color or clarity of the diamond. If you price it based on the appearance of the treated diamond, it will cause the price to be inconsistent with the actual value.

Consumers have the right to know whether they are going to buy natural diamonds, imitation diamonds or laboratory-made diamonds, and whether the diamonds have been treated to enhance their appearance.

The gia diamond certificate ensures that the diamonds that consumers purchase are worth the money.
