Gemesis, the Florida-based synthetic diamond company, currently only produces the laboratory grown diamonds in yellow and orange colors. The company is working on production techniques to produced pink and blue synthetic diamonds. It hopes to have that process developed by the end of this year. Gemesis is also working on process that would eventually allow it to grow white diamond crystals in the 5 to 10 carat range that are in greater demand worldwide. These larger sized synthetic diamonds are probably at least three years away from commercial production.
Gemesis has recently updated their web site to provide educational information about their company and synthetic diamonds, including the jewelry brands carrying Gemesis Cultured Diamonds.
