Sapphire Color Guide

Color can be quite subjective, especially in colored gemstones. Below is our guide to how we classify sapphire colors on our website.

We use color-calibrated cameras to photograph each gem to showcase their truest color. However, sapphires can appear slightly different under varying lighting conditions. Because of this, we recommend submitting a video request once you’ve narrowed your selection to four stones, so you can view them on hand in both natural and incandescent lighting.
