Diamond is well-known for its substandard rigidity and transparence and is honored “the Queen of Jewelry” all over the world. Being the symbol of success, elegance, loyalty, eternity and trueness, diamond has been popular among large amount of people nowadays. And its fantastic and various shapes and colors have made it the most beautiful and valuable jewelry in art and collecting area.
There are four basic standards for estimating the value of diamond: carat weight, clarity, color and cut. Carat weight is the unit of weight. One carat weight is equal to 0.2g. The more a diamond weighs, the more it values. Clarity represents the transparency of diamond and it’s classified into 13 different ranks: FL, IF, V, VS1, VVS2, VS1, VS2, SI1, SI2, SI3, P1, P2, and P3. Almost all the diamonds contain a little bit of impurities, and the rank of clarity is determined by the position, size and quantity of those impurities. As it is extremely difficult to get a pure diamond, the value of a diamond is gradually increasing with the increase of its clarity just as the boat will be in a higher place when the water is rising. Color is a crucial factor that influences the choice of a customer in a very sensitive way. A colorless diamond is the best one. Some colored diamonds such as red, pink, and blue, are the treasures of diamonds. Cut directly affects the appearance of the diamond. A diamond in rough is lightless and worthless. Only when the diamond is cut and processed with carefulness and earnest can it be a glittery and rare one.
According to its rough appearance, different diamonds should be cut into different shapes. Nowadays, the most favored shapes are circle, oval; lam tip, heart-shaped, pear, square, triangle and beryl.
The great characters of diamond have brought out its use in a broad application, from drilling for exploration to sharp knives for cutting. What’s more, diamond is a material that does not react to other substances easily; therefore, it is of great potential to be the carrier of other chemical matters, especially in medical fields. In addition, when diamond is processed by excellent experts, it can be a marvelous art and it can be the best decoration.
