Judging Diamond Quality

What to Look For

If you want to start judging the quality of diamonds, you must first learn and understand the 4 C's, which has four properties of diamonds that give the gem stone is the total value. 4 C-quality diamonds are color diamonds conviction, clarity, carat and cut.

Judging Color

Most diamonds are considered ideal if they are transparent, or colorless. Diamonds that are classified as colorless is the most expensive GIA certified diamonds. The colors of diamonds are marked with an alphabetic system that starts with "D" and ending with "Z". From white diamonds to yellow diamonds, completely colorless diamonds fall into the "D" and "E" quality, full-color; fancy diamonds are at the other end of the alphabet, the "Y" and "Z".

There are two main ways used to judge jeweler’s diamond quality based on color. You can leave a set of reference rocks and find the closest match between the diamond and the stone to determine its content reference letter. Moreover, the jeweler can use a colorimeter, which can electronically measure the color of the stone and determine its content in a third year.

Judging Clarity

The clarity diamonds refers to whether the diamond is clear through, or if it's minor flaws and cloudy areas within the gem. It's actually very rare to have a diamond with perfect clarity and no absolute wrong, but most diamond flaws are not visible to the naked eye and can not be seen with a magnifying device.

The Gemological Institute of America (GIA) uses a magnification of about 10x when judging diamond quality based on clarity and give GIA certified diamonds label. There are treatments to make a diamond appear nicer than it really is and the treatments should lower the overall price of the diamond, it is important to do your research before buying a diamond to be sure not spend more than you should.

Judging Carat Weight

The carat is the term used to describe the weight of a diamond and GIA diamond prices calculate using diamonds carat. One carat equals 200 milligrams of weight. A single diamond, with a large amount of carat weight is more expensive than the equivalent of several carat stone. This is because the search for diamonds is a much rarer event. So if you want a diamond ring 2 carat, for example, you may decide to go with a half-carat diamond surrounded by small diamonds that add up to year and a half carats for a total of 2 carats! Judging by the quality of the diamonds in the amount of carats is difficult due to different shaped stones, and stones with different levels of clarity, the price will be different, even if they have the same amount of carats.

Judging Cut

One of the most important factors in judging the quality of diamonds is judging by the cut of a diamond. It 'important, because the quality cut diamond is more brilliant, and reflects light beautifully, but the diamond is cut, at least for the overall effect of a diamond.

To judge the quality of the diamond the size of a diamond, look at the stone in a well lit. If the light appears to be the stone and bounce, showing a bright surface reflection, diamond has a good cut. The angles and shapes of a diamond are important to judge the quality of the diamonds and the overall appearance of your GIA diamond.
