There are numerous terms and phrases that a person needs to know about when it comes to buying a diamond. Not knowing what the different terms mean about diamonds can lead to a person being ripped off when they buy a diamond – and diamonds are expensive, so there is a chance that you could lose a lot of money when you buy the wrong diamond or buy from a source that is not trustworthy. Cut quality, color grade, clarity and carat weight, which are known as the 4 Cs of a diamond, are some of the most common terms, but there are other terms that you should also educate yourself on. Today, we would like to talk about a particular phrase, called “diamond symmetry” that is often used on a diamond grading certificate.
What Is Diamond Symmetry
Diamond symmetry is a term that is used to describe the alignment of a diamond’s facets. The better the facets are aligned, the better symmetry score the diamond receives. A diamond with a good symmetry also looks better and more visually appealing than a diamond that has a low symmetry rating. When an appraiser grades the symmetry of a particular diamond, they look at numerous factors, such as:
- Whether the edges of the diamond’s facets align with the girdle of the diamond.
- Whether or not the facets are symmetrically aligned on the outside of the diamond.
These are only two factors that are taken into consideration when a diamond’s symmetry is graded, but they are the two most significant elements that a person should look at when buying a diamond.
There are a few common problems that appraisers often observe when they inspect a diamond to grade it professionally and to determine its value. The problems that are directly related to the symmetry of a diamond that is being inspected may include:
- The diamond may have an off-center culet.
- The table of the diamond might be off-center.
- The pavilion and the crown may not be well aligned.
- The girdle might have a wavy appearance.
- The outline of the diamond’s girdle may be “out-of-round”.
- The facets of the diamond might be misshapen.
All of these factors can affect the visual appearance of the diamond and they may also have an impact on the value and quality of the particular diamond.
When it comes to choosing a diamond based on its symmetry, it is important to note that there is not a significant difference in appearance between some grades, but the prices do defer. For example, a diamond with an “excellent” symmetry rating will cost more than a diamond with a “good” symmetry rating, but they will appear similar to the naked eye. When it comes to the lower grades, however, such as “poor” symmetry and “fair” symmetry, differences can often be detected without the need for magnification. Thus, if you are buying a diamond at a higher budget, but still wish to save as much money as possible, you can opt for a diamond with a “good” symmetry grade without sacrificing visual appearance. On the other hand, you should try to avoid opting for a diamond with a “poor” symmetry rating if you do have the option to choose one with a “fair” symmetry grade.
A diamond is graded based upon a variety of qualities that are observed during an appraisal process. While the 4 Cs of quality are considered to be the most essential elements that has a direct impact on the value of the diamond, other factors, such as the symmetry of a diamond, can have a significant impact on the appearance of a diamond. Thus, considering all the terms used on the certificate of the diamond is essential if you want to get the best value for your money.
