By duplicating the conditions within the Earth, including temperature, pressure and chemical makeup, laboratories can grow gemstones. These laboratory-grown, Chatham 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.
