Chatham Created Alexandrites

Lab-grown alexandrites

Chatham created alexandrites are stunningly beautiful with amazing color change. They are the affordable alternative to mined alexandrites.

Alexandrite, the birthstone for June, is beautifully mysterious. Alexandrites exhibit the unique phenomenon known as Color Change. Under warm light Chatham created alexandrites are a reddish-purple while under natural white light they turn a beautiful teal green.

Chatham lab-grown alexandrites exhibit excellent color change because they are grown in a controlled environment in their natural crystal habit, shown left. They are not imitations, rather they are REAL alexandrites carefully grown. Top quality natural alexandrites with excellent color change are rare and extremely expensive. Thankfully, Chatham created alexandrites cost a fraction of the price of mined alexandrites.
