Chatham Created Rubies

Lab grown rubies

Chatham Ruby Crystal​Chatham created rubies rival the color of the finest Burmese rubies. Some call it pigeon blood red. We call it beautiful! Rubies are sister to sapphire. Both belong to the gem species Corundum. It is the presence of the trace mineral chromium that gives rubies their rich red color. Rubies rate 9 on the Mohs scale of hardness. So they are very durable, making them ideal jewelry.

Chatham lab grown rubies are not cheap flame fusion or pulled rubies. They grow in their natural crystal habit in a controlled environment. Because they are carefully grown, you can expect your Chatham created ruby to have gorgeous color and consistent quality. All Chatham rubies are gem quality with no inclusions visible to the naked eye.

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.
