A truly a remarkable gemstone, Alexandrite jewelry transforms from a striking teal reminiscent of a Caribbean ocean, to a fascinating magenta in incandescent light. Alexandrite is well known for displaying one of the most remarkable color changes in the gem world — outside in daylight, it is a serene bluish-green. Inside in lamplight, it is a red gem, with a warm raspberry tone. Natural alexandrite is tremendously rare, so we use only lab created alexandrites in our jewelry to keep it affordable for you to wear this stunning stone. They are physically identical to their natural counterparts, with deeper, more saturated colors, and a more dramatic color change!
