This is by far the most popular shape of diamond and has been around for hundreds of years. When diamond cutters work with this shape, their goal is maximum brilliance and shine.

These diamonds are rising in popularity by the day, and you can buy them in both square and rectangular shapes. Take a closer look at these diamonds and you will see a combination of oval and old mine cuts.

Just like round diamonds, oval diamonds have a brilliance you can really see! Oval diamonds are quite popular and appear frequently in rings and other jewelry items. If you’re looking for a traditionally cut oval diamond, the length-to-width ratio should be between 1.33 and 1.66. You can ask your jeweler to tell you the exact length and width of the diamond so you can imagine its shape when viewed from the top.
