The name diamond derives from the ancient Greek Αδάμας (adamas) "invincible", "untamed", from Α- (a-), "un-" + δαμάω (damáō), "to overpower, to tame". They have been treasured as gemstones since their use as religious icons in ancient India and usage in engraving tools also dates to early human history. Popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world ecomomy, and innovative and successful advertising campaigns. They are commonly judged by the “four Cs” : carat, clarity, color and cut.

Black Diamonds : An exotic type of diamond may have come to Earth from outer space, scientists say. Called carbonado or “black” diamonds, the mysterious stones are found in Brazil and the Central African Republic. Because of their odd appearance, the diamonds are unsuitable as gemstones. But they do have industrial applications and were used in the drill bits that helped dig the Panama Canal.
