Is moonstone an orthoclase?
Is moonstone an orthoclase?
Moonstone is a variety of the feldspar-group mineral orthoclase. It’s composed of two feldspar minerals, orthoclase and albite. At first, the two minerals are intermingled. Then, as the newly formed mineral cools, the intergrown orthoclase and albite separate into stacked, alternating layers.
Is Peach a moonstone orthoclase?
It is a variety of orthoclase, and most famous for its adularescence effect. Alternating feldspar layers build up within the stone during formation, which allows light to glide across the layers of the gem, producing this signature effect.
What is the rarest color of moonstone?
Moonstone is a variety of orthoclase feldspar, which is a sodium aluminum silicate. Moonstones can occur colorless, blue-wjite, white and pale shades of apricot and peach. The rarest and most expensive moonstones will be colorless with a floating blue color or schiller that seems to hover above the stone.
What is an orthoclase stone?
Orthoclase, also known as K-spar and K-feldspar, is a common potassium feldspar mineral that crystallizes in the form of masses, small prismatic shards, elongated crystals, and thin plate-like layers. It can form on most granites and pegmatites, as well as being one of the main chemical components of Moonstone.
What color is orthoclase?
| Orthoclase | |
|---|---|
| Color | Colorless, greenish, greyish yellow, white, pink |
| Crystal habit | Can be anhedral or euhedral. Grains are commonly elongate with a tabular appearance. |
| Twinning | Typically displays Carlsbad twinning. Baveno and manebach twins have also been reported in orthoclase. |
What does fake moonstone look like?
Sometimes fake moonstones made of glass have round air bubbles, which cannot be observed in a real gemstone. Fake moonstone looks semi-transparent and milky. Some fakes are warm to the touch. An opalite is the most common fake of moonstone and opal.
Is moonstone the same as rainbow moonstone?
While rainbow moonstone is closely related to moonstone (remember that feldspar connection), they are technically NOT THE SAME. Rainbow moonstone is essentially translucent labradorite and often has black tourmaline inclusions. Rainbow moonstone is not in fact moonstone.
Who should not wear moonstone?
Since Moon is incompatible with the planets Rahu and Ketu, the moon stone and pearl should not be worn along with hessonite or cat’s eye.
How can I tell if my moonstone is real?
The natural moonstone will have a blue luster and, most importantly, a flickering inside – an irisation. Also look at light at an angle greater than 15 degrees, as moonstone cannot refract light at an angle greater than 15 degrees. If a stone shines at different angles it is a fake.
Is orthoclase rare or common?
Orthoclase is a rare gemstone that belongs to the feldspar group, which also includes moonstone, amazonite, spectrolite and labradorite. Therefore, orthoclase is sometimes also called “K-spar”.
What does orthoclase symbolize?
Orthoclase is an important tectosilicate mineral which forms igneous rock. The name is from the Greek for “straight fracture,” because its two cleavage planes are at right angles to each other. The gem known as moonstone is largely composed of orthoclase.
Where can Moonstone be found?
Moonstones are found all across the globe in areas of feldspar mineral concentrations. These minerals are typically mined in areas of extremely old rock, such as in old mountain chains of the Appalachians and Europe’s southern Alps. Though they are mined, moonstones are found virtually everywhere on the planet.

What is Moonstone gemstone?
Moonstone is a gem variety of orthoclase feldspar, known as potassium aluminum silicate.
