Color Change Spinel
watch this stone change color in front of your eyes!
Color Change Spinel is a rare, phenomenal gem that changes color in front of your eyes. When you want two (or more) gems for the price of one…!
These gems are usually so light-sensitive that they display different colors in each different lighting condition.
The most significant changes in color are from florescent light (blues, greys) to incandescent light (pinks, purples). Daylight almost always shows a mix of each gem’s inherent colors, which can be considered a third color. Today’s newer LED lighting sometimes shows a fourth color too.
Color Change Spinels are rare above 1cts. Small inclusions that are eye-visible don’t significantly affect the price when it comes to phenomenal gemstones like these – the beauty and strength of the change is far more important.
For centuries Spinels were confused with Rubies and Sapphires, especially since they are found in many of the same sources.
One of the most famous gemstones in the world, the ‘Black Princes Ruby’ in the Crown Jewels of England is actually a Red Spinel!
Notable sources of Color Change Spinel include Tanzania, Burma and Sri Lanka.
Spinel is a durable gemstone with a hardness of 8 on the Mohs Scale and can easily be used in all types of jewelry.
Spinel is the new birthstone for August, together with Peridot. It also celebrates the 22nd anniversary and comes in a wide variety of colors, giving lots of options for August!
