What is the International Colored Gemstone Association?

The International Colored Gemstone Association (ICA) is a non-profit organization and the only worldwide body specifically created to benefit the global colored gemstone industry. ICA was founded in 1984 and now comprises over 700 gem industry leaders from mine to market, including miners, gem cutters, suppliers, retailers, trade associations, gemological laboratories, academia, museums, and more from 47 countries who are devoted to advancing and promoting the knowledge and appreciation of colored gemstones.

ICA’s global network works to develop a common language for promotion and consistent business standards necessary to improve international communication and trade of colored gemstones.

Over the years ICA has provided direct access to the source for colored gemstones and related information. There is no other international organization with the same collective access to, and knowledge about, all levels of the colored gemstone industry.
