Congratulations! You have found a Pink Diamond! The word Diamond comes from the Greek adamas, meaning "unbreakable", "proper", or "untamed".
A chemically pure and perfectly structured diamond is transparent with no hue or color. The colors occur from chemical impurities and/or structural defects. However, naturally colored pink diamonds actually obtain their hue from the way the light reflects along the growth planes in the diamond. Pink diamonds are one of the more valuable fancy colored diamond, along with blue diamonds.
Diamonds can be found in a variety of colors including yellow, pink, green, red, blue, brown, and black. "Fancy color" diamonds are valued on a different scale than colorless diamonds.
Diamonds have been treasured as gemstones since their use as religious icons in Ancient India. Diamonds are the hardest known natural material on the Mohs scale with a hardness of 10.
