How to Choose the Perfect Diamond Shape

Your Complete Guide from Sparkling Carat

When it comes to selecting an engagement ring or any diamond jewelry, one of the most personal and impactful decisions you’ll make is the shape of the diamond. Not to be confused with the cut, a diamond’s shape refers to its silhouette, and each shape tells a unique story.

At Sparkling Carat, we know that the perfect diamond shape reflects your personality, style, and story. This comprehensive guide will walk you through the top diamond shapes, how to choose the right one for you, and what each says about your style.

What Is Diamond Shape?

Diamond shape refers to the outline or silhouette of a diamond when viewed from the top. Unlike "cut," which defines how well a diamond’s facets reflect light, shape is purely aesthetic—and totally up to your personal preference.
