Diamond Cut

What Is The Cut Of A Diamond?

Have you ever noticed how many surfaces a diamond has? A diamond’s cut refers to how well-proportioned the dimensions of a diamond are, and how these surfaces, or facets, are positioned to create sparkle and brilliance. For example, what is the ratio of the diamond’s diameter in comparison to its depth? These small, yet essential, factors determine the diamond’s beauty and price.

Are You Wondering Which Diamond Cut Is Best? It All Starts With Your Budget.

No single diamond is perfect for everyone—but all of our customers, whether they’re eyeing a .50-carat or a 16-carat diamond, want as much sparkle as their budget allows. Of the the 4Cs (cut, colour, clarity, carat), cut has the greatest influence on a diamond’s beauty and sparkle. Even a diamond with a flawless clarity grade (no blemishes or inclusions) can look glassy or dull if the cut is too shallow or deep. So, when determining what diamond to buy, go with the best cut grade that you can afford.

Crown: The top portion of a diamond extending from the girdle to the table

Girdle: The intersection of the crown and pavilion which defines the circumference of a diamond

Diameter: The measurement from one girdle edge of a diamond straight across to the opposing side

Pavilion: The bottom portion of a diamond, extending from the girdle to the culet

Culet: The facet at the tip of a gemstone. The preferred culet is not visible with the unaided eye (graded "none" or "small")

Depth: The height of a gemstone measured from the culet to the table

 

Diamond Cut And Diamond Shape Are Not The Same Thing

Although these terms are sometimes used interchangeably, diamond cut, and diamond shape mean different things.

Diamond cut assesses light performance of a diamond and is based on a combination of factors: proportions, symmetry, and polish (the overall surface condition of a diamond’s facets).

Diamond shape is related to the outline of a diamond.
