Sapphire August Birthstone

August’s birthstone, sapphire, is among the most popular gemstones in the world, and for good reason!

These beautiful stones are typically thought of as being a vivid, violet-blue color, but sapphires can present varying colors in different lighting and when viewed from different angles.

What’s more, sapphires actually occur in every color of the rainbow — except for one.

Here are some interesting facts about sapphires:

1. Sapphires Come In Every Color Except Red

Sapphires are a variant of the mineral corundum, which is something they share with rubies.

Every color of corundum is considered a sapphire, with the exception of red corundum — that’s a ruby!

Blue is the most common color of sapphire, but the stones can also be yellow, green, white, orange, pink, or purple.

The rarest and most valuable color of sapphire is called “padparadscha” and is a mix of pink and orange.
