Diamond Shape Vs. Diamond Cut
Diamond Shape and Cut may seem like they’re the same concepts, but are actually two different things.
Diamond Shape refers to the outside outline of the diamond’s figure. For example, Pear shape is literally the shape of the diamond. While Diamond Cuts are the facets, symmetry, dimensions and reflective qualities of the diamond. Cuts refer to how deep or shallow the diamond is cut or how brilliant or fiery a diamond looks. The Cut is essential to the pricing of diamonds.
When you are shopping for diamonds, first start with what shape of the diamond you want. After determining your favorite shape, move onto what cut of diamond fits your style and preference.
