Rough Diamond
The hardest natural material, fresh from deep underground/Geology & Minerals
A typical gem-quality rough diamond is a translucent octahedral crystal about 1 cm across, formed at depths of 150 to 200 km under pressures of about 5 gigapascals and temperatures above 1,300 K. Diamonds are brought to the surface by volcanic eruptions through kimberlite pipes. Despite being the hardest known natural substance (10 on the Mohs scale), diamond can be shattered by a hammer strike along its cleavage plane.
