At Isaac Jewelers we feel it's important for our customers to be educated about diamonds they purchase. We are going to do a 4 part blog series on the 4 C's. The first one will be cut of the diamond.
The cut scale ranges from excellent to poor. A polished diamond’s beauty lies in its complex relationship with light: how light strikes the surface, how much enters the diamond, and how, and in what form light returns to your eye.
3 attributes help to form a beautifully cut diamond: brightness, fire and scintillation.
-Brightness is the combination of all white light reflecting from the surface and interior of the diamond.
-Fire describes the “flares” of color emitted from a diamond.
-Scintillation describes the flashes of light you see when the diamond, light, or the observer moves.
A polished diamond’s proportions affect its light performance. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation.
There are 5 levels of cut grade: Excellent, Very Good, Good, Fair, and Poor. The most common found in jewelry stores are excellent, very good and good. These 3 cut grades show the best and tend to look the best in jewelry.
