When you’re looking for a diamond engagement ring, or another piece of diamond jewelry, you will likely see the phrase “cut” pop up in your research. This is because the cut of a diamond has a significant impact on its appearance.
A diamond’s cut grade refers to how well a diamond has been optimized for visual appeal. A poorly cut diamond will appear unappealing due to light leaks, visible cracks along the girdle, and other defects that impact its sparkle. When comparing two diamonds with similar clarity grades but different cut grades, it’s easy to see which one has been given more attention to detail during the cutting process.
Curious about whether your future partner prefers diamond cut good vs very good? Here are some details on cut grade and how it impacts the appearance of your favorite precious stone.
What Are Diamond Cuts?
The most popular diamond cuts are the round, princess, emerald, Asscher, and pear cuts. The round cut is the most brilliant, while the princess cut is versatile and the emerald cut is elegant. The cut of a diamond affects its appearance, with different cuts having different characteristics. Round diamonds are the most popular type of cut.
Differences Between Very Good and Good Cut Diamonds
The main difference between a very good-cut diamond and a good-cut diamond is an approximately 10% decrease in brilliance and sparkle. This is because the proportions of a very good-cut diamond are slightly different than those of a good-cut diamond. Specifically, a very good-cut diamond has a smaller table size and a shorter crown (where the girdle meets the pavilion) than a good-cut diamond. GIA-certified diamonds are graded according to the “ideal” proportions established by the GIA. However, the “ideal” proportions are not achievable in every diamond. A gemologist can determine the cut grade of a diamond by examining its proportions and comparing them to the GIA standards.
Which Is Better?
At the end of the day, the difference between a very good-cut diamond and a good-cut diamond is a matter of preference. A very good-cut diamond will definitely sparkle more than a good-cut diamond, but it’s also more likely to have visible flaws such as light leaks and visible cracks along the girdle. A good-cut diamond won’t sparkle quite as much as a very good-cut diamond, but it’s also less likely to have optical defects that impact the sparkle of the diamond. Clearly, there is no “better” cut grade. It all comes down to personal preference and the amount of “sparkle” you want your diamond to have.
The cut grade of a diamond refers to the proportions and the number of facets that have been cut into it. A well-cut diamond maximizes the brilliance and the beauty of the stone. When comparing two diamonds with similar clarity grades but different cut grades, it is easy to see which one has been given more attention to detail during the cutting process.
