April's birthstone also represents strength. It is said to be the "ultimate gemstone" because it is the hardest mineral in existence, even tougher than the sapphire or the ruby.The most coveted of all birthstones most are colorless but colored varieties do exist.There are many kinds of diamonds: transparent, translucent or opaque; ranging from colorless to sooty black, with many colors in between. Mostly transparent diamonds, colorless or tinted, are used as jewelry.The purest diamond is so transparent and colorless that no other stone or mineral in the world can compare. Whenever light strikes a diamond, the particles of light are so evenly dispersed that it seems a bright "flame" burns inside the stone. Clarity of thought and purity of heart is what this trait represents.The color of a diamond depends on the kind of impurities embedded inside it. Yellow diamonds, for example, betray minute quantities of nitrogen, while boron imparts a bluish hue.
