Feldspar Metaphysical Healing Properties

The feldspar group includes the microcline, orthoclase and plagioclase feldspars. The Feldspar Group belongs to the Silicate Class of minerals. They commonly occur as prismatic crystals in aggregate groups.

Orthoclase Feldspar Geology

Orthoclase is the feldspar mineral of pink granite, the #6 mineral of the Mohs hardness scale, and one of the two minerals that comprise Moonstone.

What is Feldspar? Industrial Minerals Association ...

Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based upon feldspar content. The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8).

Gemstone Information Feldspar: Meaning and Properties ...

Feldspar group consists of mainly 3 mineral species: Microcline feldspar a mineral species with chemical composition of KAlSi2O8. Amazonite is the variety under this mineral species. Orthoclase feldspar mineral species with chemical composition of KAlSi3O8. Moonstone (white, gray, peach etc.) is the main variety under this mineral species.

K Feldspar: Mineral information, data and localities.

Indicates mineral may be doubtful at this locality. Good crystals or important locality for species. World class for species or very significant. (TL) Type Locality for a valid mineral species. (FRL) First Recorded Locality for everything else (eg varieties). Struck out Mineral was erroneously reported from this locality.

Feldspar minerals make up over 50% of Earth's crust.

Most feldspar minerals have a Mohs hardness of approximately 6 to 6.5 and a specific gravity between 2.5 and 2.8. They all have a vitreous luster that is often pearly on cleavage faces. The accompanying table shows the generalized physical properties of the feldspar mineral group.

Where Is Feldspar Mined

Gemstones Feldspar. The premier gemquality feldspar is the red labradorite, known as sunstone, mined in Oregon. Large quantities of gemquality labradorite, most of it waterclear, straw yellow, or yellow sunstone, has been produced from deposits in southeastern Oregon for many years.

Orthoclase Feldspar Geology

Physical Properties of Orthoclase. All feldspar minerals are usually translucent to transparent, display two directions of cleavage that intersect at approximately 90 degrees, have a vitreous to pearly luster on cleavage faces, and have a specific gravity between about 2.5 and 2.6.

Plagioclase Wikipedia

Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture", in reference to its two cleavage angles).

A Detailed Overview of Feldspar: Types, Properties, and Uses

The mineral feldspar can be subdivided into different types, depending on the proportion of the elements sodium, calcium, or potassium. The color of the resulting mineral depends on its composition. The higher the sodium content, the lighter the color of the mineral. Alternatively, the higher the calcium content, the more colored the mineral is.
