Rough Diamond Tutorial & Guide
Much energy is needed for carbon to turn into diamond, which is a thermodynamically stable form of carbon when it is under high pressure (tens of thousands of atm) and
reaches more than 1832°F.

Map of diamond deposits
Discover the different exploration and prospecting techniques for diamond deposits, the systematic exploration of vast areas, and prospecting when related to hydrography.
Diamond exploration
Discover the different types of diamond deposits, which are: primary deposits, secondary deposits (eluvial and alluvial), and marine deposits.
Diamond exploitation
Discover the different techniques used for processing diamond ores: crushing, screening, scrubbing, concentration, and collection.
Processing diamond ore
After they have been recovered, diamonds need to be sorted into categories before being sold, namely diamonds that need cleaving, diamonds that need sawing, diamonds that
need to be cut, and diamonds destined to industrial uses.
Sorting rough diamonds
There are five operations that are necessary for turning a rough diamond into a polished diamond: cleaving, sawing, bruting, cross working, and brillianteering.
Cutting rough diamonds
Producing countries - along with importing and exporting countries, industry - have come up with a certification scheme for the international trade in rough diamonds.
