Answer:
Diamonds were formed billions of years ago and are extremely rare because so few are able to survive the difficult journey from the pits of the earth to reach the earth's surface. From the diamonds that are being mined today, only about 50 percent are thought to be high enough quality to be sold on the diamond market.
