The process of mining, refining and grading gemstones like diamond is very interesting. In various countries of the world there are various kinds of grading systems for diamonds. However the most popular grading system, one that is recognized and respected by diamond traders and manufacturers, is the grading system made by the Gemological Institute of America. One of the most innovative processes that is now used in the grading of diamonds is the application of ten times the magnification as the practice standard for the grading system. Now in most places diamonds are graded after careful scrutiny under 10 x magnifications before being sent to Fine Jewelry Manufacturers and Diamond Jewelry Manufacturers.

Another way of grading and knowing the worth of a diamond is by the Four C process. The 4 C Process is actually a mnemonic device and consists of color, cut, clarity and carats. This process is very popular in grading nowadays as it helps the consumer to know whether the diamond is a precious stone, a semi precious stone or fake.

A faulty cutting procedure can spoil the beauty of the diamond while an excellent cut can enhance it. The first thing to do before cutting is to see the shape of the diamond. Most of these stones are by nature oblong. Some can be oval as well. Large diamonds are given special cuts known a Princess cuts. Others are given the general Square cut. Most of the modern diamonds that we see nowadays in jewelry have a round outlines. These are symmetrical and triangular in shape along with facets in the shapes of kites.

After a diamond is mined it is transported and treated. It is first treated with heat. Heat is useful as it can improve various qualities of the stone like color and clarity. Originally it was done by the miners themselves near the mines, but today due to the requirement and demand of better and high quality diamonds, the heat treatment is done in special facilities. During this process the diamonds are protected by the application of boracic acid, without which the diamond can be completely burned. After heating the diamond is Waxed. During this process the stones are treated with either wax or oil to further enhance the colors. The next treatment process is fracture filling process. Lead glass is filled into the diamonds to improve their appearance. Before the diamond is cut it must be planned well as it in this stage that the value of the stone is determined. The diamond is marked in places where it is to be cut. Size, direction, shape and clarity must all be incorporated before the cutting can begin. It is then sawed and cleaved manually. After this it is polished finely by machine. Finally it is polished and dispatched to Fine Jewelry Manufacturers.
