Lab Grown Emerald Cut Rubies

Chatham created emerald cut rubies

Chatham Ruby Crystal​The rich red color of Chatham lab grown emerald cut rubies rivals the color of the finest Burmese rubies. Some call it pigeon blood red. We call it beautiful!

Chatham lab grown rubies are not cheap flame fusion or pulled rubies. They are flux rubies. Chatham was the first company in the world to commercially produce flux ruby in 1958. Flux rubies grow in their natural crystal habit. So the crystal structure is identical to mined rubies. Most mined rubies on the market are cloudy and unattractive. Mined rubies with exceptional color and clarity are rare and very pricey. Because Chatham rubies are carefully grown, you can expect your Chatham created emerald cut ruby to have gorgeous color and consistent quality. All Chatham created rubies are gem quality with no inclusions visible to the naked eye. Best of all, Chatham emerald cut rubies cost a fraction of natural mined rubies.

Pictures not actual size. Ruby is denser than diamond, so it weighs more for the same physical size. Because carat is a measurement of weight, not size, it’s important to order colored stones based on physical size rather than carat weight.

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.
