Like all diamond shapes, the cut is an important factor in overall quality and is arguably one of the most important of all 4Cs. The terms “shape” 그리고 “cut” are often used interchangeably, but there are some differences between the two. While shape refers to the general silhouette of a stone, cut grade refers to the quality of stone and how it interacts with light. Let’s first dive into the different grades of diamond cut.
The Cut Scale consists of six grades: Ideal, Excellent, Very Good, Good, Fair, and Poor. Most diamonds are between Very Good and Good quality, though you may come across those that are Ideal or Poor. While a Poor grade means the diamond was cut either too deep or too shallow and didn’t reflect light well, an Ideal grade means that it was cut perfectly and features the most amount of light return. This can also play a part in the Oval bow-tie effect. Ideal and Excellent diamond grades are less likely to have the bow-tie dark spot, making them the best cut options for Oval stones—or any stone shapes, really.
Now that you understand the Cut Scale a little more, you know that the best cut for an Oval diamond is Ideal. Although that is true, that doesn’t mean that you have to opt for an Ideal grade to get a beautiful diamond. Very Good and Good cut grades still result in a stunning, sparkly diamond that will look dazzling for a lifetime and longer. The difference is they may cost quite a bit less but have a greater chance of having the bow-tie effect. 그래서, when determining which cut grade is right for you, ask yourself which is more important: perfect quality or an affordable price? Whichever cut grade you opt for, ensure that it checks off your box for price point and appearance.
