What is Iceland spar used for?
The name calcite comes from the Greek word meaning “lime.” Other names for the mineral and its varieties: stone flower, stone rose, paper spar, stalactite, stalagmite, heavenly stone, paper spar, anthraconite. Physical properties:
a) color: white, yellow, pink, greenish,
b) hardness: 3,
c) density: 2,6 – 2,8 g/cm3,
d) degree of transparency: transparent (Iceland spar), translucent, opaque,
e) line – white, light gray,
e) gloss – glassy, matte,
g) fracture – stepwise,
h) system – trigonal, ditrigonal-scalenohedral type of symmetry,
i) cleavage-perfect according to (1011). Calcite crystals have a wide variety of shapes: scalenohedral, lamellar, prismatic, columnar, rhombohedral. There are a lot of simple forms known, the main ones being (1010), (0112), (2131), (0001), (1011), (0221), (4041), (1120), etc. Doubles of (0001) are common. , (0112), including mechanical, polysynthetic according to (0221), occasionally according to (1011). Composition
Formula – CaCO3. Chemical composition – content (in%): CaO – 56; CO4 – 44; impurities of iron, manganese, strontium, etc. are noted. Features of education. Various drusen and adhesions are observed. Granular dense calcite aggregates make up many hydrothermal veins, carbonatite bodies, and marble strata. Calcite is the main (and sometimes the only) mineral of carbonate sedimentary rocks, especially biogenic rocks, and, along with aragonite, is part of the solid parts of corals and many other organisms. It also forms stalactites, stalagmites, helectites and similar bushy aggregates in caves. Main deposits
Dalnegorskoye field in Primorye, Evenkia. Medicinal properties
In folk medicine, there is an opinion that calcite can alleviate diseases of the digestive system. The effect of the mineral on the diseased organ depends on the color of the stone. For example, orange calcite improves digestion and helps with spleen pathology. Red calcite helps with intestinal diseases. Yellow calcite relieves kidney pain. Calcite beads set in silver help with colds. Lithotherapists suggest that calcite pendants, as well as rings worn on the little finger of the right hand, help with heart disease. Calcite affects the crown chakra. Magical properties
Calcite helps its owner to reveal extraordinary abilities – to become clairaudient, clairvoyant, clairvoyant. In order to achieve this, you should meditate with the stone daily from 5 minutes to 12 hours. Experts say that even simply wearing a mineral expands a person’s consciousness, gives him the opportunity to foresee the consequences of new beginnings, new acquaintances, and allows him to comprehend the true attitude of other people towards the owner of the stone. Calcite becomes very attached to its owner, and if a person loses or gives it away, he blocks his magical abilities for a long time and refuses to serve the new owner. Calcite can only be passed on by inheritance. Moreover, the testator must prepare the calcite for the coming change – he must “introduce” the stone to the future owner. This is done using a simple ritual. The owner places the calcite product (or jewelry with it) in the hand of the heir and pronounces the ritual phrase: “I give you away with gratitude for your service. Serve him (name) as you served me” (the phrase is pronounced three times). After this, the new owner of the stone should hold the calcite under running water (to wash away the connection between the stone and the previous owner) and, concentrating on the mineral, establish contact with it. If a person has no desire to reveal his extraordinary abilities, meditation is not needed – the connection will be established after a week of constantly wearing the stone. Astrologers say that calcite can be worn by people born under any zodiac sign except Scorpio. He will refuse to serve the latter, since Scorpios by nature are prone to practicing black magic, and calcite is a magical stone of light forces. Talismans and amulets
As a talisman, calcite is an excellent assistant for businessmen, economists, financiers, lawyers and doctors. It makes them far-sighted and protects them from professional mistakes. Astrologers advise car enthusiasts and professional drivers to have calcite products, since it is believed that the stone can protect the owner from the difficulties of the road, in particular from accidents. Application
Most often, druses of translucent white, pink, cream, and yellow calcite, which vary in appearance and morphology, are used as decorative collection material. Calcite in druses is often associated with galena, sphalerite, chalcopyrite, fluorite and other minerals. The value of such samples depends on the degree of decorativeness and rarity of all the minerals present. Very impressive are the druses of white and translucent thin-plate, intricately fused calcite crystals, as well as intergrowths of finely leafed papierspar crystals. Such collection material is widespread in calcareous skarns and hydrothermal calcite, including ore-bearing veins. Much less common are scalenohedral and rhombohedral crystals of colorless or yellow transparent calcite-Iceland spar. Colorless, golden-yellow and pink cleavage rhombohedrons of Iceland spar are very popular, allowing one to see the effect of birefringence of light, as well as containing thin mechanical twins with iridescent interference colors or decorative inclusions of white fine-fiber mordenite, bright green celadonite and other minerals. Very original examples of Iceland spar growing on finger-shaped chalcedony secretions. Determined by rhombohedral cleavage, low hardness, violent reaction with hydrochloric acid.
