Yellow Sapphire


Bright yellow to canary yellow!

Yellow Sapphire colors can range from light pastel yellow to medium yellow to a strong orangey-yellow.

Sapphires and Rubies are actually the same mineral – corundum. Pure Corundum is colorless; trace elements in different percentages are responsible for all the colors.

Sapphires are routinely treated to improve their clarity and color. However, many of our Yellow Sapphires are completely Natural and untreated (see product labelling on each gem).

Principal mining locations for Yellow Sapphire are Sri Lanka, Australia, Tanzania and Thailand.

They are durable gemstones with a hardness of 9 on the Mohs Scale and can easily be used in all types of jewelry.

Sapphires are September’s birthstone and their variety of colors offers so much choice! They also celebrate the 5th and 45th Anniversaries.

Important information

Natural, untreated Sapphire is getting harder and harder to find in the market; it sells for a premium over treated and enhanced stones
