Lab-Grown Alexandrite

Mineral: Chrysoberyl | Hardness: 8.5 | Birthstone Month: June | Anniversary: 55th

The chameleon of gemstones.

Mined alexandrite is known for its remarkable color-changing properties, displaying hues of green in daylight and shifting to a purplish-red under incandescent light. Alexandrite became Carroll Chatham's third lab-grown gemstone, making its debut in 1972. These lab-grown alexandrites possess the same chemical composition, optical properties and color-changing characteristics as their mined counterparts, exhibiting vibrant color shifts under varying light sources.

Chatham lab-grown alexandrites are highly regarded for their quality, durability and responsible sourcing. They offer a more affordable alternative to mined alexandrite while maintaining the allure and beauty associated with this rare gemstone.
