Shape Up: A Guide to Choosing the Right Diamond Shape

There are 11 diamond shapes to choose from. Which shape will you rock? 

A diamond tells a story. It says something about the one who wears it, but what statement would you like to make? Looking for something classic or, maybe something captivating? Below is the guide to the 11 basic shapes and who wore them best. This guide will help you make the most befitting choice. 

Quick note: Don’t get confused. The shape and the cut of a diamond are two different things. The shape of the diamond is how it looks (round, oval, etc.) and the cut of the diamond is the way it reflects the light. You want the most brilliance or sparkle due to the way your diamond has been cut. 

Brilliant Round: Classic, Timeless & The Equivalent of the Little Black Dress (LBT)

Description: The round or brilliant shape diamond was created in 1919. It is the most popular shape and offers the most brilliance and exceptional sparkle with 58 facets hence the name brilliant round. It is a classic shape that has been popular since its inception and is forever in style.
