About Diamond Shapes
Diamonds are cut in a variety of shapes. But how does a diamond cutter decide what shape to create? Well, a diamond cutter's number one responsibility is to preserve and maximize carat weight. And since rough diamonds can come in unpredictable shapes and sizes, the diamond cutter will create whichever shape maximizes carat weight and value.
Interestingly enough, round cut diamonds actually result in the most wastage of rough diamond carat. The other fancy shapes are deeper and tend to have longer, less uniform shaping so they capture more of the rough diamond.
While diamonds can be cut in any shape, there are 10 popular diamond shapes: Round, Princess, Cushion, Oval, Emerald, Pear, Marquise, Asscher, Radiant and Heart shape. Exotic shapes include Baguettes, Bullets, Half Moons, Trillion, Old Mine, Rose, even Horse head.
