Quartz#Rose quartz

Rose quartz is a variety of the mineral quartz. It has a pink -red color is milky to translucent and usually occurs in granular aggregates.

Rose quartz certain localities loses its color by exposure to sunlight, while the other rose quartz deposits, even after they were exposed to sunlight 50 years, have retained their color. When heated above 575 ° C loses Rose Quartz its color.

Besides the ever-present inclusions of fine fibers of a Dumortierite -like mineral often find finest rutile needles. Both mineral inclusions are often perpendicular to the prism axis ( crystallographic c axis ) oriented in the crystal grown and responsible for the occasionally observed asterism of rose quartz.

Pink Quartz: euhedral crystals (crystals with regularly developed areas) are extremely rare and free of opacifying inclusions. The color fades upon exposure to UV light, and upon heating above 200 ° C.

Rose quartz is usually processed to semi-precious stones and works of art.

Color causes

The causes of pink color with coarse, dull rose quartz and clear quartz Pink are different.

The cause of dull color rose quartz has long been controversial and many causes have been discussed, such as incorporation of manganese or manganese-containing minerals, light scattering of the finest Rutileinschlüssen, inclusions of pink minerals or interaction of iron and titanium ions in the quartz. Recent studies have proven that the finest inclusions impart a fibrous Dumortierite -like Mineral Rose Quartz its color. Dumortierite, a borosilicate, is colored by the coupled incorporation of trace amounts of iron and titanium pink.

Clear pink crystals of quartz obtained color not by inclusions, but by the incorporation of aluminum and phosphorus coupled into the crystal structure, followed by irradiation. Source of ionizing radiation in general, the decay of the radioactive isotope potassium 40K.

Education and Locations

Rose quartz is found in granitic pegmatites, where it occurs together with K-feldspar, tourmaline, cassiterite, beryl and phosphate minerals. Furthermore, there is massive rose quartz in hydrothermal quartz veins.

Clear, euhedral crystals of pink quartz are very rare. It is known, for example, the occurrence in sapucaia pegmatite in Minas Gerais, Brazil.

Esoteric

In the Esoteric Rose quartz is considered as a powerful symbol of love and fertility. It is supposed to cure physical and mental weaknesses of love life, as well as, for example, Relieve headaches, for the reason he is considered a healing stone. He also belongs to the heart chakra and to strengthen the institutions in the heart region. Furthermore, he should be able to absorb harmful radiation ( eg, water veins, electrosmog ). For the effective range in esotericism, however, there is no scientific evidence.

Warning

Rose quartz should, in contrast to otherwise claims can not be used as an infusion - stone in the sauna. Quartz is a brittle mineral generally sensitive to changing, high heat loads. Therefore, even without the infusion process itself, in which the stones are put off, again and again fragments are blasted flying as sharp fragments across the sauna room and due to the hardness of the material to cause serious injury. In addition, rose quartz quickly lose after long-term use as an infusion stone her pink staining and decay.
