How Are Diamonds Mined And Extracted From the Ground

To make mining efficient and effective, the raw rock and soil are typically not examined on-site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.
