Certified Strong Color Change Alexandrite
A beautiful stone with a superb color change. Depending on the quality of the daylight, the color ranges from blueish green to greenish blue. Under incandescent light the color is clearly reddish purple. The cutting and proportions are excellent and the stone is clean except for a few patches of silk. There was know way I could pass on this stone … the best alex I’ve seen in years!
