How to Judge a Diamond's Quality
When begin to search for a perfect diamond, We will certainly find that there is a big difference in price, and price is usually based on assessing the quality of the four Cs of diamonds, including cut, clarity, color, and carat.

Before we make a diamond purchase, we need to familiarize yourself with these terms, and we also need to find a reputable jewelry. Although we can examine the diamond yourself, we can ensure that we get value for the price only if we rely on the expertise of a specialist diamond.

Judging Cut
One of the most important factors in judging diamond quality is judging the cut of a diamond. It’s important because a quality cut diamond will be more brilliant and reflects light more beautifully, and yet the cut of a diamond has the least impact on the overall price of the diamond.

When judging diamond quality on the cut of a diamond, look at the stone in a well lit area. If the light seems to go into the stone and bounce back, showing a sparkling reflective surface, the diamond has a good cut. The angles and shapes of a diamond are important to judging diamond quality and the overall appearance of your diamond.

Not the shape of the stone, cut refers to how well a diamond’s facets are proportioned and aligned to maximize brilliance. According to Tiffany, an excellent diamond cut might sacrifice as much as 62 percent of a stone’s total weight.

Judging Color
Most diamonds are considered to be ideal if they are transparent, or colorless. Diamonds that are rated as colorless are the most expensive of diamonds.

There are two main ways that jewelers’ use when judging diamond quality based on color. They may pull out a set of reference stones, and find the closest match between the diamond and the reference stone to determine its letter grade. Alternatively, the jeweler may use a colorimeter, which can electronically measure the color of the stone and determine its grade within 1/3 of a grade.

When rating the color of a diamond, jewelers commonly use the letters D through Z. The more yellow or brown tint a diamond has, the less value it receives. The rating D represents a diamond that is colorless; while the rating Z has a yellow or light brown hue.

Judging Clarity
The clarity of a diamond refers to whether or not the diamond is clear all the way through, or whether it has tiny flaws and cloudy areas within the gemstone. It’s actually very rare to have a diamond with absolute perfect clarity and no flaws, but most diamond flaws are not visible to the naked eye and can only be seen with a magnifying device.

The Gemological Institute of America (GIA) uses a magnification of about 10x when judging diamond quality based on the clarity. There are treatments available to make a diamond appear nicer than it actually is, and the treatments should lower the overall price of the diamond so it is important to do your research before purchasing a diamond to be sure you are not spending more money than you should.

Judging Carat Weight
Carat is the term we used to describe the weight of a diamond gemstone. One carat is equivalent to 200 milligrams of weight. A single diamond with a high amount of carat weight is more expensive than the equivalent amount of carats in multiple stones. This is because finding the larger diamonds is much more rare of an occurrence.

So if you want a 2-carat diamond ring, for example, you may decide to go with a half-carat diamond surrounded by smaller diamonds that add up to one and a half carats to give you the total of 2 carats! Judging diamond quality by the amount of carats is difficult, since different shaped gemstones, and stones with different levels of clarity will be priced differently even if they have the same amount of carats.
