The Sapphire is the Birthstone for September! Known for its deep blue color, the sapphire has been one of the most sought-after gems for centuries. Find out why both royalty and healers have sought out beautiful sapphires, the September birthstone.

Sapphire’s Color

The gemstone is best known for its striking pure-blue color, but it can range from greenish-blue to violet-blue. Part of the same corundum family as the ruby, stones in violet, green, yellow, orange, pink, and purple are known as “fancy sapphires.” Some exhibit color changes depending on the lighting.

Corundum is naturally colorless, but trace amounts of elements like iron, titanium, and chromium lead to a range of colors. Outside of red corundum (rubies), all other corundum gems are considered sapphires.

Iron and titanium are responsible for the blue color, and the more iron present, the darker the blue color of a sapphire. Yellow and orange sapphires get their color from the presence of iron and chromium, while pink sapphires are a result of high amounts of chromium. A purple color is a combination of all three trace elements.
