Dutch Gem Academy

About Us

The World Gem Foundation is a non-profit organization that was formed in 2015 with the mandate to provide quality and affordable gemmological training to students, jewellers and professional gemmologists.

Currently consisting of twelve national and regional gem academies in the United Kingdom, Holland, Scandinavia (Norway, Sweden, Finland, Denmark and Iceland), Spain, Kenya, Democratic Republic of Congo, the U.S, Canada, India, Central America (Mexico, Guatemala, Honduras, Nicaragua, El Salvador, Costa Rica and Panama), South America (Brazil, Argentina, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay, Venezuela, Guyana and Suriname) and the Caribbean (Cuba, Puerto Rico, Haiti and the Dominican Republic), we plan to establish three more academies around the world before the end of 2018.

Through our network of registered academies, students can now study gemmology through the World Gem Foundation and have their accomplishments and achievements acknowledged and recognized worldwide.

With our flexible study schedule, three diploma programs (Career Gemmologist, Diamond Professional & Coloured Gemstone Professional) and courses ranging from basic through advanced gemmology to gem identification, diamonds and coloured gemstones, the World Gem Foundation will help you meet the needs and demands of our ever-changing industry.
