Chatham Created Alexandrites

Lab-grown alexandrites

Chatham Alexandrite CrystalChatham 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.

Our Work In Madagascar

Changing lives for children and their families

We get our hands dirty!

In 2014 Michelle went to Madagascar to learn about the geology and mineralogy of the country. She was excited to visit some of the mining localities she learned about in her studies to be a Graduate Gemologist. However, it wasn't the sparkly colorful gems that caught her eye. Rather, it was the children...the little gems of Madagascar. Michelle founded in 2015. She visits Madagascar for about two months each year doing humanitarian projects, including clean water, sanitation, education and hygiene.
