Alexandrite

Tsarstone collectors guide

Certified Natural Alexandrite Oval 1.09cts.

Medium dark very strongly bluish green in daylight (fluorescent), and medium reddish purple under incandescent light, the color change is excellent and attractive under any kind of light. The cut, polish, and proportions are good. No major inclusions are apparent but one part of the stone is somewhat silky and this may also account for the superior color change. A complimentary AIGS mini certificate is included with the purchase of this stone.
