A rare and unique stone.

Our team spent months searching for the perfect deposit of black dolorites. After exploring multiple locations around the Western Cape, South Africa, we finally discovered one of the rarest and highest-quality deposits of this unique stone.

Our deposit is characterized by its distinctive dark colour and fine-grained texture, making it particularly well-suited for use in the metrology industry. Unlike other stone, this black rock is rare — and a deposit both large enough and of such high quality to be commercially viable is exceptionally difficult to find.

Precise, sustainable, accountable.

At our quarry, we use state-of-the-art techniques and equipment to produce raw dimensional blocks — mining the mineral from a large sill-shaped formation and preparing it for use across many industries and projects. Our team of experts carefully monitors the entire process to ensure the stone is extracted safely, sustainably and in an environmentally accountable way.

We take great pride in the fact that our deposit of black dolorite is among the most precious and sought-after granite in the world. Use our stone, and you can be sure you are getting a truly unique, high-quality product that will stand the test of time.

Engineered to measure.

The metrology industry relies on precise measurement to ensure products and equipment are manufactured to the highest standards of accuracy. Our black granite — a highly stable, durable material — is perfect for the production of precision metrology machines.
