Round Lab Created Alexandrite

Our lab-created alexandrite is not only shockingly beautiful – but it also has the exact same chemical and optical properties as its much more expensive natural counterpart! This magical gemstone turns from reddish purple to blueish green when you walk outdoors. In addition to giving you perfect color change (almost unheard of in natural stones), our round lab created alexandrite is also cut to exacting standards for max beauty and brilliance. Durable and unique, it makes an incredible, mystical engagement ring center stone. Learn more about alexandrite here!

Because they are created by Chatham, your lab-created alexandrite will be among the most beautiful in the world, with the best cut and color change on the market. Once you select your size (choose from a classy .50ct (5mm) up to a whopping 2.7ct (9mm)), a gemologist will handpick the best stone from at least 5 top-grade alexandrites!
