What is the purpose of a diamond?

Because diamonds are very hard (ten on the Mohs scale), they are often used as an abrasive. Most industrial diamonds are used for that purpose. Small particles of diamond are embedded in saw blades, drill bits, and grinding wheels. These tools are then used for cutting, drilling, or grinding hard materials.

What does Culet mean?

In gemology, a culet is a flat face on the bottom of a gemstone. During the 14th century, after the adoption of the table cut, a further facet was added to the bottom of the cut parallel to the surface of the table. The term used for these bottom facets derives from the Latin word for bottom, culus.

Should a diamond have a Culet?

Since a large culet can negatively affect the appearance of a diamond, it's best to stick to diamonds that have no culet. This is often referred to as a pointed culet, as the bottom of the diamond has a point instead of a flat surface. These grades all provide a diamond with optimal brilliance.
