The main difference is definitely the colors they show when hit with light. Labradorite is a dark grey, black crystal. It shows a multitude of wonderful colors such as yellow, green, purple, red, or blue when you look at it under the light. Moonstone, on the other hand, is usually white, peach, green, pink or blue.
Is moonstone actually labradorite?
It’s known in the trade as rainbow moonstone, despite the fact that it’s actually a variety of labradorite rather than orthoclase. A variety of labradorite is sometimes called rainbow moonstone. Sanidine is another feldspar mineral that can include adularescent gems called moonstones.
How can you tell the difference between a moonstone and a rainbow moonstone?
Moonstone is an orthoclase and albite mineral while Rainbow Moonstone is a form of Labradorite. Both of them can have various colors, ranging from different shades of green and blue to pink and white. While moonstone can be opaque, translucent or transparent, Rainbow Moonstone will always have a milky appearance.
Can moonstone be faked?
Fake moonstone is free from any fractures or inclusions and looks perfectly homogeneous. Moonstone fakes are hard to identify at first glance. Fakes are made of specific glass and even have their own name – opalite.
How can you tell good quality moonstone?
A good moonstone should be almost transparent and as free of inclusions as possible. Inclusions can potentially interfere with the adularescence. Characteristic inclusions in moonstone include tiny tension cracks called centipedes. They are called this because they resemble those long, thin creatures with many legs.
What does pure moonstone look like?
The finest real moonstones possess a colorless, semi-transparent to nearly transparent appearance and vivid blue adularescence that’s sometimes referred to in the trade as blue sheen. To fully display the adularescence of moonstone, it is commonly cut as a cabochon.
Is labradorite a grey moonstone?
While they may look similar, labradorite stones and moonstones are not the same. They are, however, referred to as ‘sister stones’. They are both members of the feldspar mineral family, but labradorite is classified as a plagioclase feldspar, while moonstone is an orthoclase felspar.
What are the inclusions on rainbow moonstone?
Characteristic inclusions in moonstone include tiny tension cracks called centipedes. They are called this because they resemble those long, thin creatures with many legs. The most-typical moonstone inclusions are stress cracks that gemologists call centipedes.
Are there fake moonstones?
Does moonstone glow in the dark?
Moonstone Exhibits the Optical Phenomenon Known as Adularescence. Adularescence is the optical phenomenon that causes the extraordinary glow on the surface of moonstone. The light moves across the stone much like moonlight would glide across a large body of calm water.

What does high quality moonstone look like?

Do all moonstones glow in the dark?
This could make some believe that moonstones are phosphorescent. However, moonstones are not phosphorescent materials, and therefore do not glow in the dark. Such materials are unique in the fact that they emit stored energy in the form of light.

What is the finest Moonstone?
The finest moonstone is a gem of glassy purity with a mobile, electric blue shimmer. Characteristic inclusions include tiny tension cracks called centipedes.
What type of mineral is Moonstone?
About Moonstone. Moonstone is a variety of the feldspar-group mineral orthoclase. During formation, orthoclase and albite separate into alternating layers. When light falls between these thin layers it is scattered producing the phenomenon called adularescence.
What is a twinned Moonstone?
This twinned moonstone shows good crystal form with flat faces. Moonstone is a variety of the feldspar-group mineral orthoclase. During formation, orthoclase and albite separate into alternating layers. When light falls between these thin layers it is scattered producing the phenomenon called adularescence.
