Cutting Critique

Jeffrey M. Bertman
Graduate Gemologist

It is often said that “cut”(along with “carat weight,” “color,” and “clarity,” the “4Cs”) is a characteristic that largely determines the value of a diamond. Thus, it is important to inspect the thickness of the diamond’s “girdle,” which is the edge around the periphery of the gemstone where the upper and lower sections meet. While diamond is legendarily hard, it is also brittle. Therefore, a diamond with a thin girdle is considered to be a liability because it is more vulnerable to chipping. However, if the girdle is too thick, its value is also somewhat reduced because the gemstone will look a bit smaller than a diamond of the same weight with a girdle of normal thickness. The cut of the diamond is extremely important because it has the greatest influence on the diamond’s brilliance. And when it comes to diamonds, brilliance is what makes diamonds “a girl’s best friend.” We are located at 1402 Hancock Street, Quincy Center, where our jewelry professionals will help you select the exact piece for that special someone.
