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.
