I have already received the ring. It is absolutely breathtaking. Actually I did not know what breathtaking is until I did see the ring. Thank you so much. It turned out perfect!

Physically, Optically & Chemically Identical to natural sapphire!

lab created huge oval pink engagement ringWe 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.

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.

Identical 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.

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.

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

Lab-grown sapphires are available in a few shades of blue, pink, and yellow. Red (ruby) is also an option.
