Explore the World of PrinsGems 
Our Universe of Precious Stones.

We offer an array of natural coloured gemstones collected by Dr Petre Prins over the past 50 years.  Our collection includes natural gemstones ranging from sapphire, diamond, ruby, emerald, tanzanite to beautiful tourmaline, aquamarine and other unique gem species. Each Prinsgem larger than a carat carries a Gemmological Grading Report issued by a GIA graduate gemologist. This sets us apart from most dealers who may have gem experience but not certified gemmological qualifications. Our irrefutable gemmological expertise guarantees your peace of mind.

Certified Gems for Sale – A Unique Opportunity

Do you need a quality gem at an affordable price? We regularly offer special bargains on certain gems that crowd our inventory.  Selected parcels of sapphires, garnet, citrine and emeralds are often available at give-away prices.  For gem collectors, jewellers, goldsmiths or any admirer of beautiful stones, our special offers provide unique opportunities to extend your inventory.

Loose Certified Gems – For Bespoke Jewellery

Loose gemstones provide the opportunity to create personalised jewellery items. You can select the size, shape, and type of loose gem to fit your budget and craft a piece that is uniquely yours. Coloured gemstones are perfect for a ring, pendant or in earrings.

Invest in Precious Gems

Internationally, the price of precious gems are given in US$ per carat.  The dollar value of commercial gems have been remarkably stable while the price of exceptional and rare types have increased dramatically over the past decade. Purchasing precious gems is seen as a wise investment, especially in countries whose currency has been depreciating against the dollar. Our gemmologists will assist you in selecting quality gemstones that will delight you and also hold lasting value.
