Parti Sapphires
Bi-color gemstones are a fascinating demonstration of the effects of a changing natural environment during the formation of a given stone. People are often familiar with the unique charm of bi-color tourmaline, but not many know about the gorgeous variety of parti sapphires.
The specific conditions necessary to create sapphires are incredibly rare. Sapphires are in the corundum family, and are essentially formed by cooling magma inside igneous rock. The terrain of the region must be free of silicone, one of the most common elements on earth.The right conditions are only found in a handful of places around the world. Sapphires are mined in Australia, Nigeria, Myanmar, Thailand, and even here in the US in Montana!

Did you know that sapphires come in every color under the sun? Pure corundum presents as a clear, misty white gemstone. Other trace elements and minerals (like titanium, iron, cobalt, and copper) must be present in the rock during the growth process to create other colors and hues.

Commonly confused with color-changing sapphire (where a sapphire exhibits a strong change in color and appearance in different types of light), parti sapphires display distinct zones of two or more colors, no matter the light or angle from which they are viewed.
Most parti sapphires display a coupling of three possible hues; blue, yellow, or green. Some particularly rare sapphires will display a trio of all three colors. We occasionally even see an unexpected hint of orange in a parti sapphire!
