Prospecting for Diamond Deposits - The GemHunter's Guide

Diamonds form rare gemstones commercially mined from kimberlite, lamproite and placer deposits primarily around old continental cores known as cratons. Minor diamond mineralization is also found in other rock types - such as some lamprophyres, but so far, these remain uneconomical. When diamond-bearing rocks erode, they leave behind trails and clues for geologists and prospectors. Learn these clues well, because diamond deposits are very difficult to find.
