Cut & Appearance

How Cutting Influences Padparadscha's Appearance

A padparadscha's shape, cutting proportions and facet arrangement influence how it reflects light and how its colour appears.

Even stones with similar colour may look different in brightness and contrast. Compare samples of similar size under the same lighting when selecting a cut for your design.
