Have you ever heard about the surprising reality linked with the nature of diamonds? By nature, the world’s most prized gemstone is nothing but a metastable allotrope of carbon. Carbon is usually considered a commonplace material with little value attached to it. Then what transforms carbon into a highly valuable material is the different arrangement of the carbon atoms, forming a face-centered cubic crystal.
Carbon is not that much hard. It is the strong covalent bonding between the carbon atoms that make diamond the hardest substance on earth. This strong covalent bonding,in unique pattern,also renders it other superlative physical qualities.
Diamond occurs in a variety of different colors, ranging from black and completely colorless to yellow or brown. Sometimes, it may also be found in pink, purple, red and blue hues. Do you know the color of diamond crystal can have a great effect on its worth? It’s true.
The color serves as a determining factor for the value of this precious stone. The colorless diamonds are the most expensive and most valued ones. The black ones, on the other hand, are relatively less expansive. Such colored diamonds are considered as “fancies”. Owing to their rarity, some fancy diamonds have become most valuable materials in the world.
In fact, there are four factors that contribute to determining the value of a diamond. These are: color, cut, clarity and carat weight. In other words, you can say that “the four Cs” collectively determine the worth of this gemstone.
