The Truth About Color Changing Gemstones
COLOR CHANGING GEMSTONES
Color-changing gemstones are a small group of gems that exhibit the color change optical phenomena. Color changes in these stones can be due to the shifting wavelengths, and they are called photochromism.
Color-changing gemstones have been popular for centuries because they offer an easy way to create jewelry with dramatic but subtle colors that could not otherwise be achieved through traditional methods like dyeing or painting. They offer an alternative to diamonds if you want something different than white for your engagement ring.
Color-change garnets make stunning rings by themselves, while sapphire rings often feature diamond accents on the band. These stones are also popular for pendants and earrings. This means you could get a pair of matching color-change garnets or sapphires. Hue changes in these gems are typically best observed in direct sunlight or controlled lighting conditions to reduce glare.
The color change is determined by the gem’s absorption spectrum, which is determined by its color, clarity, cut, and size in addition to environmental factors. Color change in the same gemstone can also vary in different lights because gems are often cut differently to show off their best features when viewed under only one light source.
Sapphires, Alexandrites, and Garnets are some of the most well-known color-changing gemstones.
Alexandrite is a type of chrysoberyl that exhibits a strong color change from green in incandescent light to red in daylight. The stone was first discovered in the Ural Mountains, hence its name from the Russian word рубить саблю, meaning “to cut with a sword”.
In 1796, at the order of Empress Catherine II of Russia, a consignment of rough emeralds was sent to Amsterdam for cutting and found to contain the new gemstone.
Alexandrite is a rare stone and has been called “the queen of gemstones”. Color-changing natural Alexandrites are very expensive, but colorless Alexandrites can be found at affordable prices. They are beautiful color changing gemstones.
