Alluvial Diamond Mining The Brilliance Blog

Alluvial Diamond Mining is the process of extracting diamonds and other precious stones from the sand and mud found along river banks. The diamonds and precious stones have been carried by a river’s force from their source in a Kimberlite rock formation and deposited along the river’s banks. Small scale miners sift through the sediment deposits to find the precious stones using shovels

DIAMOND MINING AND THE ENVIRONMENT FACT SHEET
