Diamond Shapes

Types of Diamond Shape

There are two main types of diamonds, brilliant and step cut. When purchasing a step cut diamond it's best to choose a higher quality stone as sometimes inclusions can be seen. With brilliant diamonds it is not as necessary to choose such a high quality stone as the brilliance of the stone would un able you to see any small inclusions.

Brilliant diamonds are, Round, Oval, Marquise, Radiant, Princess, Pear, Cushion and Heart shape.

Step Cut diamonds are Emerald cut and Asscher cut.

Although the diamond shaped listed above are what they are known as to the general public, the diamond laboratories sometimes call them different names such as Square Modified Brilliant for the Princess Cut and Square Emerald Cut for Asscher Cut and so on. This is because some of these names are the branded names given to certain diamond shapes and the diamond laboratories are not permitted to print these names.

Diamond Ratios, Table% and Depth%

Diamond ratios are very important. A ratio is the measure of how square or rectangular a diamond is. The only diamond in which the ratio is not important is the round brilliant diamond.

For all the other shapes, it's very important, because the ratio of a diamond affects its beauty. To get the ratio of a diamond just divide the length by the width.

Here are the recommended ratios, table% and depth% for the diamond shapes.
