Lab grown diamonds are physically, optically, and chemically indistinguishable from mined diamonds. They provide exceptional value and typically cost 30-40% less than mined stones of the same size, cut and quality.
Chatham gemstones are known for their superior quality. By duplicating the conditions deep within the Earth, including temperature, pressure and chemical makeup, the Chatham laboratory can grow gemstones over a year’s time. These laboratory grown gemstones are physically, optically and chemically identical to their mined counterparts. The only difference is that the gem growing process takes place above the ground, rather than below.
