When thinking of diamonds, many will immediately think of the classic round diamond shape. No doubt that the round brilliant cut is the most popular shape but if you’re looking for something different, there are plenty of other shapes available. A diamond’s shape refers to its physical form and each diamond shape is very different, possessing unique characteristics. Even though shape is not a part of the 4 C’s of Diamonds, this element will have an impact on the appearance of your diamond. Since each diamond shape is cut to different specifications, they reflect light differently, giving each shape a unique fire and brilliance.

Diamond Clarity

Diamond clarity indicates the presence or absence of inclusions and blemishes within a diamond.

Diamond Culet

The culet is the tiny facet or point at the bottom of a diamond, where the pavilion facets meet.

Diamond Girdle

The girdle is the thin perimeter of a diamond, dividing the crown (top) from the pavilion (bottom).

Diamond Certification

A Diamond Grading Report includes all of the stone’s defining characteristics and scores.
