What Are Diamond Shapes ?
Diamond shapes refer to the overall form or outline of a diamond—such as round, oval, or square. This is different from “cut,” which refers to how well the diamond’s facets reflect light. There are many different diamond shapes available today, each designed to enhance brilliance, size appearance, and overall aesthetics.
The right shape doesn’t just affect how your diamond looks – it also influences:
Sparkle and light performance
Perceived size
Ring style compatibility
