Chatham

Architects of the Gem Growing Industry

Chatham gemstones are known for their superior quality thanks to the continuous technical refinement over our 80-year history. By duplicating the conditions deep within the Earth, including temperature, pressure and chemical makeup, our 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. Our technology allows us to provide gemstones at a fraction of the price.
