imitation diamonds

lab created diamonds, fake diamonds

 

Certain laboratory-created gemstones, such as lab-created moissanite, also resemble diamonds and may not be adequately detected by the instruments originally used to identify cubic zirconia. An imitation diamond is one that looks like a diamond, but has a totally different physical makeup.

Imitation diamonds, such as cubic zirconia, resemble diamonds in appearance but are much less costly. Cubic Zirconia is created by heating yttrium oxide and zirconium oxide. These stones have remarkable clarity and if cut correctly are extremely hard to tell from a diamond with the naked eye.


The physical properties of hardness, refractive index and specific gravity are very different from a true diamond. Simulant, imitation is a material that imitates the appearance of a gem without duplicating its properties (glass, plastic, etc.). Artificial synthetics: these are the manufactured stones that have no natural counterpart and include: strontium titanate, yttrium aluminate (YAG) and cubic zirconia.


 

The cubic zirconia is extremely popular, by far the most popular of the imitation diamonds there is.

With high quality natural diamonds continuing to command high prices, imitation diamonds are still a market force.

A synthetic diamond is one that was created in a lab and has very similar physical properties to a natural diamond

The simplest method to detect imitations consists in tracing a black line on a quite white paper sheet and to place the table of the stones to be tested on the black line. If you see the black line through the stone, it's an imitation. Be careful, with cubic zirconium oxide, synthetic rutile, fabulite and certain doublets which escape this rule. Ask your jeweler if he has the current testing equipment to distinguish between diamonds and other lab-created stones & imitation diamonds.
