How to Decide on a Diamond Shape
Each diamond has its own unique characteristics, just like a fingerprint. Once a diamond is recovered from kimberlite, it is cut into various shapes, the shape is decided on the basis of the inclusions and the raw form of the diamond procured; which also determines its size. These major and minor specifications impact the final look of the stone.
The diamond shape also determines its reflection and refraction, as the shape is directly linked to the cut and the cut to its brilliance. These shapes are given names such as round, oval, heart, pear, which are named directly after the shape, whereas some others have fancier names like princess for square, baguette for rectangle, cushion for pillow shaped diamonds and so on. The diamonds however have one important feature and functionality – reflection, the shape decides how the diamond will be cut to maximize light return.
A diamond shape can also increase or decrease its value. The round being the most popular shape, followed by princess, pear, oval and baguette. However baguettes and tapers are used mainly for settings rather than solitaires.
