    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. Even after extraction, the rough diamond is still far from being set in an engagement ring.
