Van Hilten & Co. established in Dar es Salaam, is a family-run business with over 30 years experience in mining & metals, agriculture and real estate. We have business operations and partnerships in seven countries across Europe, Africa and the Middle East.

Our trusted reputation and exclusive position within mining & metals has enabled us to build a worldwide network in fine coloured gemstones and minerals. We specialise in both the sale of cut gemstones, and the creation of bespoke custom-made jewellery pieces.

In addition to the Big Four - diamonds, emeralds, rubies and sapphires - Van Hilten & Co. sets the world benchmark when it comes to Tanzanite. We mine, source and cut the finest and highest quality Tanzanite ourselves: from local sources in Tanzania to the hands of international clientele.

With our ethical extraction standards, expert cutters and rare collection of gemstones, we are able to provide all our clients with the finest cut gemstones, as well as the highest quality ‘one-of-a-kind’ jewellery pieces.
