Due to the high value of diamonds a system had to be created that would compare one diamond to another in a standard way. In 1940 is a system was created by the Gemological Institute of America. This system grades in four ways: carat, color, clarity and cut.

The carat of these beautiful gems and the gold karat are not the same thing. They are both the measurements, but a diamond’s carat measures weight, while gold’s karat measures of the purity.

A perfect diamond is colorless. GIA certified diamonds are rated on a scale from D to Z, with D having the least amount color. The difference in their color in a jewelry store are not apparent to the untrained eye because they are so subtle, but it will be noticed in the price. As the price of them lower, the color becomes more yellow.

Since these gemstones are organic, there may be some flaws called inclusions in them. It is extremely rare to find one that doesn’t have at least some small flaw in it under magnification. The extent that a diamond is without flaws, is called clarity.

The cut is what gives it the beauty. A diamond in the rough, straight from the ground, is almost unrecognizable as the diamond you see in the jewelry store. With a GIA certified diamond, the cut is graded from poor to excellent, and the most popular shapes are oval marquise an emerald. As the value of the diamond increases it becomes more color less more flawless and sparkly.
