Some gems, like alexandrite, are almost impossible to find in nature today, much less in the sizes and quality people dream of owning.Synthetic alexandrite can be created in a variety of ways including flux growth, Czochralski method, or floating zone method.Synthetic gems have the same chemical, optical, and physical properties of their natural counterparts, but are a more cost-effective alternative to a natural gem.

||Flux grown synthetic alexandrite might have metallic platelets from the platinum crucible, veil like inclusions, flux inclusions, flux filled cavities, straight or angular growth lines layers of dust-like inclusions parallel to seed plate.Czochralski method pulled stones will have needle like inclusions, curved striae and small black like gas bubbles.Floating zone or hydrothermal stones will have dark gas bubbles, long flat liquid inclusion and a swirled appearance. |
