Diamonds are formed deep within the Earth: between 100 km and 200 km below the Earth’s surface.The temperatures they are formed at are about 900 – 1300 C.

The cut of a diamond determines its brilliance. 

There is no single measurement of a diamond that defines its cut, but rather a collection of measurements and observations that determine the relationship between a diamond’s light performance, dimensions, and finish.
