In the 1920s, a boy with a dream to grow diamonds began the historic experiments that would launch the world’s leading lab-grown gemstone company.
After many years of research, Carroll Chatham, a young chemist in San Francisco, discovered the secret of growing emerald crystals. By duplicating the conditions deep within the Earth: temperatures, pressures and chemical makeup, his laboratory succeeded in growing gemstones over the course of a year’s time.
These gemstones possess the same physical, optical, and chemical structure as their mined counterparts.
Today, Chatham is the world’s leader in lab-grown gemstones, creating the finest quality sapphires, emeralds, rubies, diamonds and a rainbow of other gems set in unique jewelry designs that are always stylish and never mined. We are one of the few vertically integrated brands in the industry, which allows us to offer exceptional quality and value. That’s why more people choose Chatham than any other lab-grown gem.
Our complete line of jewelry includes color fashion, bridal, diamond fashion and initial pendants, as well as a variety of loose lab-grown diamonds up to around 5 carats. But no matter how beautiful the product, it’s the brand partnership that really drives sales and profits.
Chatham supports retailers with a comprehensive marketing strategy aimed at communicating the brand effectively to the consumer. Through progressive thinking and innovation, Chatham has developed programs intended to generate sales and ensure our retail partners success.
