Chatham Created Opals

Lab grown opals

Chatham Opal Color Chart

Opals exhibit a phenomena known as Play of Color, referring to the flashing rainbow color in opal. Top quality natural opals with excellent play of color are rare and valuable.

From rare and precious dramatic black opal, to crystal, and to white opaque opal with its vast galaxy of color, the Chatham Created Opal is available in a wide range of colors. Pierre Gilson Sr. of France first invented the synthetic opal producing process in 1974. This process is considered the truestChatham created black opal gemological process in the world today. Unlike natural mined opal, Chatham created opal is much more durable and not prone to breaking. And also the colors are natural with no treatment or enhancements. Best of all, Chatham created opal is a fraction of the price of mined opal of the same quality.

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.
