Color Change Sapphire
rare…rare…rare…
the best of both world’s…
watch this stone change color in front of your eyes!
Color Change Sapphire 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 quite light-sensitive so they display different colors in each different lighting condition.
The most significant changes in color are from florescent light (blues, greens, greys) to incandescent light (pinks, purples, reds). Daylight almost always shows a mix of each gem’s inherent colors, which can be considered a third color.
The presence of the trace element vanadium is believed to cause this effect.
Color Change Sapphires are rare above 2cts. Most of our Color Change Sapphires are completely Natural and untreated (see product labelling on each gem).
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.
Principal mining locations for Color Change Sapphires are Tanzania, Madagascar, Sri Lanka and Montana (USA).
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.
