Guess the Sapphire

Gemstones are placed into mineral families based on the chemical composition and crystal structure. (I know, I know, a riveting start to my blog, but I promise it gets interesting!) Sapphire is part of the Corundum mineral family which is made up of Aluminum and Oxygen. In its purest form, Corundum is actually colorless but trace elements during the growth phase will cause various colors.

Did you know that Corundum comes in every single color of the rainbow including black, brown, and gray? In fact, the gemstone we call Ruby is actually a red variety of Corundum. The blue variety is always called Sapphire, while the other colors (except for red) are called Fancy Sapphires. What trace elements cause the other colors in Corundum? Let’s find out!

· Blue: Iron & Titanium

· Red (Ruby) and Pink: Chromium. The more Chromium is present, the deeper the color will be. Lighter amounts make it pink!

· Orange: Chromium & Iron

· Yellow & Green: Iron. The more Iron is present, the greener it will be. Lighter amounts make it yellow!

· Purple: Chromium, Iron, & Titanium

Sapphire is not only a beautiful gemstone, but it is also very durable making it perfect as a colorful diamond replacement in an engagement ring. There aren’t any other gemstones besides Diamond that can stand the test of time like Sapphire (or Ruby) can.
