Moonstone feldspars silicates Gemstones index

Moonstone. >> Group (s) : feldspars, silicates. See the pictures : Back. The moonstone is composed of alkaline feldspar, mainly potassium in other words orthoclase, in its variety "adularia". This is actually a microperthite resulting from a microscopic phase separation of platelets from a sodium feldspar, the albite, in the orthoclase during the

Moonstone ~ Learning Geology

Moonstone is the most well-known gemstone variety of orthoclase feldspar, a potassium aluminium silicate. It is a transparent to opaque oligoclase, a variety of plagioclase albite and sheet mica. Moonstone is known to exhibit a distinct sheen under certain lighting conditions, and it is the sheen which renders moonstone one of the most remarkable gemstones available today. In fact, its name is

Black star moonstone meaning and properties video

Black star moonstone is a sodium potassium aluminum silicate with the chemical formula (Na,K)AlSi3O8 and belongs to the feldspar group. Its name comes from a visual effect, or sheen, due to the light diffraction within a micro-structure consisting of a regular of feldspar layers (lamellae).

Moonstone & Feldspar Gemstones Gemgazer

Feldspar is a chemically complex group of minerals with a wide range of members. The two main Feldspar groups that are of interest to gemologists are Alkali Feldspars and Plagioclase Feldspars. The Alkali varieties include Orthoclase, a monoclinic Potassium Aluminium Silicate with varieties such as Moonstone and Sanidine. Microcline, a triclinic

OPOD Moonstone adularescence

Moonstone is a feldspar, within the stone there are domains of alternating layers of slightly different composition. Feldspars are complex sodium potassium aluminium silicates. Albite (sodium rich) and orthoclase (potassium rich) are compositional extremes or end members of feldspars. As a feldspar melt cools, albite solidifies first leaving an adjacent potassium rich liquid which then forms an orthoclase

Gemstones I Love Feldspar Group: Moonstone,

The Feldspar group includes several very popular gemstones Amazonite, Moonstone, Sunstone, and Labradorite among others. In the earth’s crust, feldspars may be more abundant than all other minerals combined. The majority of the common feldspars fall into two groups, (1) the alkali feldspars potassium aluminum silicates (KAlSi3O8) and sodium

The name moonstone is used as a trade name, to designate a mineral from the group of silicates and the family of feldspars. It comes in crystals, pieces or aggregates grained, mostly coarse. Its luminescence is variable according to the colour (bluish or orange) but remains weak. It sometimes presents effects of adularescence (phenomenon of refraction of the light which creates nice

Feldspars Gems Sources Wholesale Gemstones & Jewelry

Moonstone, with its mysterious white or blue sheen, is one of the most familiar gem varieties of a large group of minerals called the feldspars. Feldspars are the most abundant minerals in the crust of the earth. All are aluminum silicates containing calcium, sodium, or potassium. The potassium members include orthoclase and microcline. The other feldspars, forming the plagioclase group, have been

The feldspars are a large group of aluminum-containing, monoclinic or triclinic silicates that comprise the majority of the earth’s crust. They are classified by way of the relative quantities of potassium, calcium and/or sodium that are present within their respective compositions, with the primary divide occurring between the calcium-containing

Feldspar vs Moonstone What's the difference? WikiDiff

As nouns the difference between feldspar and moonstone is that feldspar is (mineral) any of a large group of rock-forming minerals that, together, make up about 60% of the earth's outer crust the feldspars are all aluminum silicates of the alkali metals sodium, potassium, calcium and barium feldspars are the principal constituents of igneous and plutonic rocks while moonstone is...

It occurs mainly in orthoclase feldspars with tiny segregated albite lamellas (»Perthite Moonstone«), but can also occur in albite. If albite segregates orthoclase feldspar, it is called »antipertite« (trade name: »Albite Moonstone«). If it segregates oligoclase, it is called »peristerite«. As the latter originates mainly from Tanzania, it bears the trade name »Tanzania Moonstone
