Understanding Diamond Shapes vs Diamond Cuts

Before exploring the different diamond types, it is important to understand two commonly confused terms.

Diamond shape refers to the outer appearance or outline of the stone.

Examples include round, oval, pear, cushion, emerald, and princess.

What is a Diamond Cut?
