Diamond Clarity Basics
Clarity is a term that’s used to describe the clearness of a diamond. A perfect diamond with perfect clarity is rare, and most flaws that exist in jewelry grade diamonds cannot be seen without looking at them through a jeweler’s magnifying loupe.

About Diamond Cut
The term diamond cut does not refer to a diamond’s shape. It describes the diamond’s proportions, such as its depth and width and the uniformity of its facets–all characteristics that control brilliance, durability and other features we look for in a quality diamond.
A good cut is essential to a diamond’s beauty. If the cut is of poor proportions, even a diamond with outstanding color and clarity will not display the sparkle that diamonds are famous for, because the gemstone’s components cannot interact with light as they should.
Diamond Cut Basics gives you a background in the characteristics that make up a quality cut diamond.
The Gemological Institute of America puts diamond cuts into three basic categories, and when you break it down like that, cut really isn’t confusing at all. Here’s a look at popular cutting styles you’ll encounter when you shop for a diamond.
