Chatham Lab-Grown Alexandrite

 [powr-video-slider id=ab9dadc8_1497556381]

Chatham Created Alexandrites are very close to the Russian ideal that starts with a naturally mined seed of Russian alexandrite and use a lot of chromium in the solution to make sure that the color change is dramatic. Since mined alexandrites are so rare, the natural rough is almost always cut in an oval shape to preserve carat weight. At Chatham, 80% of the rough is cut away for maximum clarity and intense color-change for a full spectrum of shapes.

The alexandrites grown at Chatham are true laboratory grown alexandrite, the famous color-change chrysoberyl variety, with the exact same physical, chemical and gemological properties as the mined gems.

Alexandrite Fun Facts: 

Unique for transitioning from green in the sunlight to red by a candlelight dinner, Alexandrite and its special qualities makes it a rare find. This beautiful gem was named after Czar Alexander II after being discovered in 1830 by Russia’s Ural Mountains, because its red and green colors resembled the uniform of the Russian Imperial Guard. Alexandrites consist of a hardness measured at an 8.5 in the moh's scale and is considered a birthstone for June.
