LAB CREATED SAPPHIRE INFORMATION


Synthetic Blue Sapphire in Pave Engagement Ring"Chatham does not make gemstones, we make environments in which crystals grow naturally."

We offer you synthetic 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 synthetic gemstones, from ruby and sapphire, to emerald and alexandrite since the 1930s.

Synthetic Pink Sapphire in Mokume Engagement Ring
A Chatham sapphire is not an imitation, but a real 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 synthetic sapphire?

  • Lab Created Ruby in Mokume Engagement RingIdentical Physical, Optical and Chemical Properties

    Synthetic sapphire has pretty much the same atomic and optical properties of a natural sapphire. 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 natural counterparts! Under laboratory conditions, computers control temperatures, while foreign materials found in the earth are eliminated from starting chemicals.

  • Lab Grown Yellow Sapphire in Mokume Engagement RingAffordability

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

  • Synthetic Pink Sapphire in Three Stone Engagement RingEnvironmentally 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.
