If you are in the market for a diamond ring for the first time, you may be wondering what gives a diamond its value. Certainly, in general, the larger the diamond, the more expensive the diamond will be, but there are obviously other factors involved when you simply look at diamonds of the same size. The following is a quick guide to the terminology that is used for determining a diamond’s value.
The size of the diamond
This is the one area that many people are familiar with. Diamonds are measured in carats, and this indicates the weight of the diamond. However, you need to keep in mind that diamonds come in different shapes. Two diamonds may be equal in carats (weight), but appear to be different sizes due to their different shapes. However, regardless of the difference in apparent size, they will have the same weight, if they have equal carats.
The shape of the diamond
No shape is inherently more valuable than another, but there can be differences within a shape due to how well the rock has been cut. For example, with the classic emerald shape, the ideal ratio of length to width is considered to be 1.35 to 1. The closer the emerald is to this ratio, the more valuable it will be.
The cut of the diamond
Diamonds are cut, and the quality of this cut is what constitutes part of its value. The cut is directly related to its beauty because an optimal cut will bend light towards the top of the diamond. This is what gives the rock its apparent sparkle. The better the cut, the more sparkle, and the more sparkle, the more attractive the diamond will be. The cut of the gem is graded from fair to good, then very good with ideal being at the top grade. A diamond cannot be graded for cut higher than ideal.
The color of the diamond
This is sort of a backwards way to determine the quality of a diamond because the highest quality diamonds do not have any color. Below this are grades that have traces of color, but you really need to be a gemologist to see it under magnification. Below this grade are diamonds that have only the slightest of color to the naked eye. After this, the color in the diamond becomes more noticeable and reflects a lower grade.
The clarity of the diamond
This refers to tiny imperfections in the structure of the diamond. Nature never makes a perfect diamond, but the closer to perfection the diamond is, the more valuable it will be. However, it should be kept in mind that this is the least influential of the factors that determine the price of a diamond.
Once you get a feel for what makes a diamond valuable, you will be a better informed buyer and have a better chance of getting a good deal. Keep in mind that the above information is only for the diamond itself. There are different possibilities of the band material, so this can add different values to the final price. Also, the better diamond dealers will have higher quality merchandise, so there is less chance of seeing some of the lower grades in diamond rings. A company like Mervis Diamond is an example of this. Like all quality dealers, Mervis offers appraisals and cleaning services too.
