Keep in mind also that carat weight is not the most important thing when it comes to an engagement ring and determining its value. The cut grade is actually what will affect the diamonds sparkle and fire the most, not its size.

The Average Clarity for a Diamond Engagement Ring

Diamond clarity refers to the basic visual appearance of the stone and what went on inside the mineral as it was being created. They call any surface defects blemishes and any internal defects inclusions. Clarity is known as one of the four C’s when it comes to diamond grading. A diamond will go under magnification of ten times which will then accurately assign the diamond its clarity grade.

Keep in mind that clarity is not the most important thing when it comes to grading a diamond as most inclusions or internal characteristics cannot be recognized by the human eye. Of course, the diamonds with the fewest inside flaws will go up in price even though compared to a diamond of a lower clarity grade will look no different.

When beginning your search a great place to start is with SI grades which stands for slightly included or VS grades which means very slightly included. These grades are great because you will only be able to see the inclusions with magnification.

Also, the shape and size of the diamond will affect its clarity. So for example, if you are considering a fancy shaped diamond like an emerald or heart shape or any type over one carat, then flaws will be more detectable and you might want to go up a clarity grade.

The Average Cut and Color for a Diamond Engagement Ring

The cut of a diamond refers to how well-balanced the dimensions of the diamond are and has nothing to do with the shape. This involves how the facets or different surfaces of the diamond are trimmed and polished to design that perfect sparkle and radiance. Things like comparing the diamonds depth to its diameter will decide its price and allure.
