Diamond Shape Guide

Where Shape Becomes Character

At LUCEN BLOOM, we believe that shape is more than silhouette ; it’s emotion in form.

It’s the first impression a diamond gives, and the lasting feeling it leaves behind.

Each shape carries a different rhythm, a different kind of beauty. Some sparkle with timeless brilliance. Others feel sculptural, unexpected, tender. And some ; like our own LUCEN Cut ; are designed not just to shine, but to mean something.

Let this guide help you discover the shape that reflects your story ; the one that feels like you
