The April birthstone, the diamond, in addition to being a symbol of everlasting love, was once thought to bring courage providing the wearer with better relationships and an increase in inner strength.
Diamonds have been admired for centuries, and some historians estimate it was traded as early as 4 BC. One of the reasons it is so admired and valued is because of the process by which a diamond must be formed well below the earth’s crust, then forced upward until it is uncovered. But before this process was understood, many ancient civilizations believed that diamonds were lighting made real on earth and thought to have many healing powers..
You probably already know of the diamond’s toughness. In fact, it’s the hardest gemstone and is made of just one element: carbon. It is simply the hardest substance known by a wide margin. It can only be cut with another diamond.
Pure diamond is completely colorless and transparent over a larger range of wavelengths. But diamonds do come in several colors, including yellow, red, pink, blue, and green, and range in intensity from faint to vivid. Generally speaking, the more saturated the color, the higher the value.
Diamond has a relatively high index of refraction which gives it the high luster. Diamond has a relatively high optical dispersion which gives diamond the "fire" that makes it so desirable. Its unique physical properties means it has the best possible luster of any gemstone when cut and polished well. So if you’re in the market for “sparkle,” the diamond is the gemstone for you.
