Lab-Created Alexandrite   Pear Faceted Stones


Created to exacting standards, using state-of-the-art gem-lab technology and minute attention to detail, this lab-created alexandrite has a chemical make-up identical to the finest natural alexandrite. It performs at the bench just as a natural stone does but, unlike natural alexandrite, this lab-created stone is heat-resistant and can be successfully cast or fired in place. Alexandrite is the birthstone for June.

The pear cut is a hybrid of the oval and marquise cuts; it is usually oriented with the point uppermost.
