Physically, Optically & Chemically Identical
to Earth Mined Sapphire!


lab created huge oval pink engagement ringWe offer you lab created sapphires from Chatham, a renowned leader in lab-grown gemstones. Founded by Cal Tech chemist Carrol Chatham (who tried to recreate diamond in his home lab at age 12!), the company has been producing gemstones in a laboratory setting, from ruby and sapphire, to emerald and alexandrite since the 1930s.

A Chatham sapphire is not an imitation, rather it is an actual sapphire grown in a human-controlled environment. This is not dissimilar from the way pearls are cultured. Once the required combination of chemical and environmental factors is duplicated from nature, the crystals grow over the course of a year, the length of time depending on the gemstone.

Why Purchase a Lab Grown Sapphire?

Identical Physical, Optical and Chemical Properties

Unless you're a certified gemologist with a powerful microscope, you won't be able to tell the difference between created and mined gemstones. Lab grown sapphires may even look better than their earth mined counterparts! Under laboratory conditions, computers control temperatures, while foreign materials found in the earth are eliminated from starting chemicals.

The new Peach Sapphire
A lab-created sapphire is less rare than a mined sapphire. As a result, they may be more suitable for conservative budgets. Price differences between Chatham created and mined gemstones of like quality are notable, sometimes as much as $100,000 per carat as in the case of colored diamonds. Lab grown sapphire is an excellent choice for those seeking an affordable precious gemstone without compromising the quality or sacrificing the aesthetic of their jewelry.


Environmentally Friendly

Because the crystal formation occurs in a lab instead of Mother Earth, there is less of an environmental impact. Go green by choosing a lab grown sapphire.

Color Choices
