Tsarstone collectors guide

Certified Natural Alexandrite Oval 1.31cts.

Grayish green in daylight and grayish wine red under incandescent light, the color change is excellent. The cutting and proportions are good with no windowing at all. Because of the strong color change, we always have to pay more for stones like this.
