The organization also allows us to buy directly from the cutters through their offices in Antwerp, Belgium, the diamond capital of the world.

The Independent Jewelers Organization itself is an organization focused on continuing education, offering seminars on both Gemology and Industry Trends, which promote consumer protection. IJO’s GIA Title Program is a comprehensive gemological and business education program available to us.
