Chatham Lab-Grown Alexandrites Since Chatham has experience growing emerald crystals, we always wanted to try growing alexandrite crystals as well. Alexandrites are so difficult to grow that it took us several years of effort to perfect the process. Our Chatham Created Alexandrites are very close to the Russian ideal. We start 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.
About Alexandrites Emerald by day. Ruby by night. Alexandrites are a rare variety of the mineral chrysoberyl that changes color from bluish-green in daylight or fluorescent light to brownish or purplish red in incandescent light.
