subject: A Brief Introduction to Diamond [print this page] Diamond is the elemental crystal formed by carbon under high pressure and temperature in deep earth. It is known as the hardest natural mineral so far.
Diamond is graded according to its Carat, Cut, Clarity, and Color. The diamond with more weight has greater value. Cut includes three aspects: cutting ratio, polishing, modification degree. Each aspect consists of five grades: Excellent (EX), Very Good (VG), Good (G), Fair, Poor. The diamond with excellent cutting ratio, polishing, modification degree is graded as 3EX. Clarity is divided into six grades: Flawless (FL), Internally Flawless (IF), Very Very Slight (VVS1and VVS2), Very Slight (VS1 and VS2), Slight Inclusions (SI1 and SI2) and Imperfect (I1, I2 and I3). Color is composed of many grades: D, E, F, G, H, I, JZ. The best diamond with the top grade of D is colorless. The more transparent the diamond is, the more valuable it is. But as an exception, the diamond with the color of pink or blueness could be priceless treasure.
Diamond is extremely valuable because of its beauty, endurance and scarceness. It is extremely costly because of its hard exploitation and intricate process. Diamond's culture is profound. It was once a symbol of braveness, power, dignity and nobility. But people today see it as a symbol of lasting love and loyalty.
The procedure of cutting diamond includes three steps: labeling, segmentation (chop cutting, saw cutting and molding) and polishing. The cutting shapes of diamond can be round, emerald-type, oval, pear-shaped, princess square, pillow-shaped, heart-shaped, eight hearts and eight arrows Jupiter shaped. Different shapes stand for different kinds of blessings.
Diamond is widely applied in the fields of industry and jewelry. Diamond can be used in sand paper, drilling and grinding tools to cut and shape other substances. Moreover, it can also be used in wedding rings, earrings, necklaces and other jewelries.
