Collection: Chatham Alexandrite Rings

When the sun shines, alexandrite is green. By candlelight, it’s red. How cool is that? Chatham crystals of alexandrite take months to grow. We’re thrilled to make this rare gem available for people like us who have always wanted one.  The Chatham Alexandrites we offer are true laboratory grown alexandrite, the famous color-change chrysoberyl variety, with the exact same physical, chemical and gemological properties as the mined gems. Some suppliers sell a chemically treated color-change synthetic sapphire as “lab grown alexandrite.”  It isn’t alexandrite and it doesn’t look at all like the real thing. It has a slight color change from blue to purple.  If you see “alexandrite” that doesn’t change from green to red, you’ll know that it is just an inexpensive imitation. ebay is full of fakes.  It makes us sad that people will buy one of these impostors and miss the chance to see the magic of real alexandrite for themselves.
