Wholestone Diamonds - Our Wholestone Rough Industrial diamonds are mined diamonds in their natural state, before any processing or polishing has occurred. The vast majority of diamonds found on our planet were formed much deeper in the earth’s interior than most other minerals, at depths of over 140km and temperatures of 900 to 1400°C in the upper mantle.

These Diamonds crystallise in the cubic system and its crystalline shapes are thus numerous, the principal ones are Octahedron, Dodecahedron and Rhombododecahedron. Wholestone diamonds are the product of choice for demanding rotary dresser applications, surface set drill bits and casing shoes. Our wide range allows the toolmaker to select the right product for the right tool.
