Other Characteristics

There are just so many factors to consider when you’re looking for the perfect diamond! The 4C’s and the diamond’s shape are especially important if you’re choosing a diamond for an engagement ring or other important piece of diamond jewelry, but there’s much more!

Diamond experts always look at characteristics like:

Depth Percentage
Length and Width

Diamond Symmetry

The precise shape and arrangement of a diamond’s facets is what we call symmetry. Diamond symmetry is one of the most important factors to consider because it has a big impact on the value of your diamond! When it comes to lower grade diamonds, symmetry isn’t necessarily a big concern. When buying higher-grade diamonds, though, symmetry plays an important role. Just like polish grades, symmetry is graded on the following scale:

  • Excellent
  • Very Good
  • Good
  • Poor

When you buy a diamond, always ask for the certificate, and look for a symmetry rating. Most people prefer diamonds with a Good symmetry grade or above. They just have that extra sparkle that makes a diamond truly beautiful!

If you’re worried about a asymmetry in a diamond, here are a few things to look for:

off center table diamond

Off-Center Table

The placement of the table (the largest facet on a diamond) should be centered at the top of the stone and needs to be parallel to the girdle (the outer edge of the diamond). If the table is off-center or not parallel with the girdle this can cause uneven angles. In this example we see the unbalanced appearance that occurs from an off-center table.

Off Center Cutlet

The culet is the small or pointed facet at the very bottom of a diamond. To check if the culet is centered, look at the diamond in the face-up position. You’ll see the lower girdle facets through the table. If the lines they form look like a perfect square, the culet is centered. If the cross bends one way or the other, the culet is not centered. In this example we see what an off-centered culet might look like.

Table & Girdle Not Parallel

Here we see another example of what happens when the table is not parallel with the girdle. As you can see, the crown angle is much more steep on one side than the other. From the top view you can actually see an off-center table.
