If you are looking at purchasing an engagement ring for your girlfriend, then you are likely considering a diamond ring. And, diamonds come in a wide variety of different options. It can be quite confusing to figure out the best diamond for you, and there are a few terms that may not be as familiar to you. Keep reading to learn what they are and also what they mean.

Cut Quality

When you think of cut, you may think of the specific shape of the diamond. However, shape and cut are not the same thing. The cut refers to the quality of the actual cutting process and many factors are taken into consideration when cut quality is determined. Specifically, the cut grade factors in the polish, symmetry, width, depth, and culet size. Culet is the term that refers to the point on the bottom of the diamond. 

When looking at cut quality, the culet should be small, which means there is a fine point on the end of the diamond. The girdle should be a bit wider, meaning that there are no sharp edges where the stone can chip or otherwise become damaged. Polish should be excellent so that the diamond does not dull and will retain a luminous finish.

When it comes to symmetry, the diamond should have excellent quality. While the other cut qualities may not have a great effect on the appearance of the diamond, this is not true of symmetry. Symmetry that is slightly off can be noticeable and will affect the overall shape of the diamond. Keep this mind when investigating the cut quality of the stone.

Fluorescence

Fluorescence is not typically a major factor when it comes to diamond purchases, but it is something that you are likely to see when asking about diamond grading. This term is used to describe a slight blue tone to the diamond that may or may not be visible to the naked eye. 

Fluorescence may or may not be seen as a desirable trait depending on the base color of the diamond. When a diamond is considered colorless, fluorescence can actually make the diamond look a bit darker or off-color. So, you do not want it in a high-end diamond. However, when a diamond is within the I to M color range, the fluorescence can make the diamond look one or two tones lighter or brighter.
