The process of creating a rare diamond starts at the mining and sorting level, where diamond miners must sift through millions of tons of earth to source small pebbles of diamond rough.

Large mining concerns like De Beers, Rio Tinto and BHP Billiton along with smaller companies like Petra diamonds mine diamond rough from all over the world and offer it for sale at their diamond tenders for manufacturers to bid on.
