In 1983, a group of visionaries got together to create the ICA which became a globally recognized and respected organization in the jewelry trade worldwide. The founding members wanted to respond to the changing reality of the gemstone business, address industry problems and challenges and improve communication and understanding within the trade.

The ICA staff serves the Board and members on all administrative responsibilities. The offices are located in New York city and Hong Kong.
