Diamond Mining and Value

Diamonds pass through a long chain before they reach a ring, and these articles cover most of it. You will find profiles of the biggest diamond companies, from De Beers and ALROSA down, rankings of the largest mines such as Jwaneng and the countries that lead output, and a look at prospects in places like Ethiopia, Nigeria and Odisha.

Buyers and investors can read how 1 carat and 2 carat prices are set, how lab-grown stones are changing the market, and why pink, red, blue and green diamonds are so rare. For hobby diggers there are guides to telling a raw diamond from quartz and to public sites such as Crater of Diamonds and Kelsey Lake. The ethics of diamond mining, from conflict stones to land damage, has its own section.
