diamond

Diamond is the birthstone of April. This gemstone is sometimes called the king of gemstones. It is said to be the hardest gemstone on earth, and its strong shine is exceptionally beautiful. Colorless is the most common, but it comes in a variety of shades including yellow, pink, blue, orange, and green.
