CUT 2017-10-15T14:14:11+00:00


The cut of a diamond is not the same as the shape, as many might believe. However, the cut of a diamond is most representative of the beauty and value of a particular diamond. When analyzing the quality of a diamond, the cut of the stone is the most technically difficult to pin down. But, it’s never hard to see the differences in light performance from one diamond to another.

In order to determine the cut of a diamond, jewelers use the GIA Diamond Cut Scale to measure:

Brightness – The internal and external white light reflected from a diamond.

Fire – The dispersion of light into all the colors of the rainbow.

Scintillation – The amount of sparkle a diamond produces, and the pattern of light and dark areas and flashes of light when a diamond is moved.

The cut grade also considers the design and craftsmanship of a diamond before providing a final cut grade, including its weight relative to its diameter, its girdle thickness (affecting durability), the symmetry of its facet arrangement, and the quality of polish on those facets.

The GIA Diamond Cut Scale for standard round brilliant diamonds contains 5 grades ranging from Excellent to Poor. As Boston’s premier fine jewelry store, our diamonds are hand selected for maximum brilliance and quality. We pride ourselves on the fact that each of our diamonds is spectacular, competitively priced and all naturally occurring.
