Common Diamond Myths

Myth: Diamonds are the rarest gems on earth.

Fact: That diamonds are presumed to be the rarest gems on earth is often due to the high prices, a belief that has been helped along by the industry. In fact, diamonds are more common than emeralds and rubies. For every carat of polished gem-quality diamond, you need to mine about 250 tons of earth. Or to put it another way, one must sift through 1000 kilograms of earth to get 5 grams of diamond. Loose diamonds are actually quite plentiful, and it is believed that there are enough for each person in the US to have a handful. However about 80% of diamonds mined, are of poor quality and used in industry for drilling, polishing and grinding other hard substances.
