Diamond is the birthstone for April and the anniversary gem for the 10th and 60th years of marriage.
The Diamond is the hardest substance on earth.
Most diamonds found in nature are between one and three billion years old.
Diamonds are the only gemstones composed of just one chemical element, carbon. Although crystal-clear, it is black when reduced to dust.
Diamonds can be completely consumed by fire at temperatures ranging from 1,400° to 1,607° F., depending on the hardness of the gem.
The easiest way to spot the difference between a diamond and cubic zirconia (other then throwing it into the fire) is to weigh it. Cubic zirconia weigh 55% more than diamonds.
