Andesine stone

Chemical formula is (Ca, Na)(Al, Si)4O8, where Ca/(Ca + Na). Anorthite is between 30% to 50%. The formula is Na0.7-0.5Ca0.3-0.5Al1.3-1.5Si2.7-2.5O8.

The plagioclase feldspars are a continuous solid solution series. It also as such the accurate identification of individual members requires detailed optical study, chemical analysis or density measurements. Refractive indices and also specific gravity increase directly with calcium content.

The stone was first described in 1841. It was for an occurrence in the Marmato mine, Marmato, Cauca, Chocó Department, Colombia. The name comes from the Andes. Due to its abundance in the andesite lavas in those mountains.

In the early 2000s, red and also green gemstones began to be marketed under the name of andesine. After some controversy, these gemstones were subsequently discovered to have been artificially-colored.

Andesine occurs in intermediate igneous rocks such as diorite, also syenite and andesite. It characteristically occurs in metamorphic rocks of granulite to amphibolite facies. The gemstone commonly exhibits texture. It also occurs as detrital grains in sedimentary rocks. We found it commonly with quartz, also potassium feldspar, biotite, hornblende and magnetite.

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. It is more properly known as the plagioclase feldspar series.

The name comes from the Ancient Greek for oblique fracture. In reference to its two cleavage angles. Plagioclase is a major constituent mineral in the Earth’s crust. It is consequently an important diagnostic tool in petrology. For the composition, origin and evolution of igneous rocks identification.

Plagioclase is also a major constituent of rock in the highlands of the Earth’s moon. Analysis of thermal emission spectra from the surface of Mars suggests that plagioclase is the most abundant mineral in the crust of Mars.
