Chatham is a renowned brand that has been at the forefront of the lab-grown gemstone industry for over 80 years. The brand's commitment to continuous technical refinement has established them as the original architects of lab-grown gemstones and diamonds. Chatham's story began with Carroll Chatham, a young and ambitious chemist, who built his first gem laboratory in his parent's San Francisco garage at just 12 years old.

After an accidental explosion during a diamond-growing experiment, Carroll shifted his focus to growing emeralds. This led to the founding of Chatham Inc. Over the years, Chatham expanded its range of lab-grown gemstones to include rubies, alexandrite, blue sapphires, and more.

These gemstones possess the same physical, optical, and chemical structure as their mined counterparts. In addition to supplying loose gemstones, Chatham also offers a stunning collection of finished jewelry. Their lab-grown gemstones, known for their high clarity grade, allow for a wide range of cutting styles, resulting in innovative designs unique to Chatham.

With their Lifetime Warranty and Certificate of Authenticity, Chatham ensures the continuation of Carroll's legacy for generations to come. As the leader in laboratory-grown gemstones, Chatham remains at the forefront of innovation and excellence in the industry
