ITEM# SPHERE-Calcite-0001
Huge 9.14 kg blue calcite sphere from Pakistan. Truly a one-of-a-kind piece for the serious sphere collector.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite.
Calcite is transparent to opaque and may occasionally show phosphorescence or fluorescence. A transparent variety called Iceland spar is used for optical purposes. Acute scalenohedral crystals are sometimes referred to as "dogtooth spar" while the rhombohedral form is sometimes referred to as "nailhead spar".
Single calcite crystals display an optical property called birefringence (double refraction). This strong birefringence causes objects viewed through a clear piece of calcite to appear doubled.
Calcite, like most carbonates, will dissolve with most forms of acid. Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Although calcite is fairly insoluble in cold water, acidity can cause dissolution of calcite and release of carbon dioxide gas. Calcite exhibits an unusual characteristic called retrograde solubility in which it becomes less soluble in water as the temperature increases. When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together or it can fill fractures. When conditions are right for dissolution, the removal of calcite can dramatically increase the porosity and permeability of the rock, and if it continues for a long period of time may result in the formation of caves.
Calcite is often the primary constituent of the shells of marine organisms, e.g., plankton (such as coccoliths and planktonic foraminifera), the hard parts of red algae, some sponges, brachiopods, echinoderms, most bryozoa, and parts of the shells of some bivalves (such as oysters and rudists). Trilobites, which are now extinct, had unique compound eyes. They used clear calcite crystals to form the lenses of their eyes.
Calcite is one of the most important minerals. It is extremely common and found throughout the world in sedimentary, metamorphic and igneous rocks. In the form of limestone and marble it makes up a significant portion of Earth's crust and serves as one of the largest carbon repositories on our planet. The properties of calcite make it extremely useful as: construction materials, abrasives, agricultural soil treatments, construction aggregates, pigments, pharmaceuticals and more.
Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis. Limestone is also formed as a deposit in caves from the precipitation of calcium carbonate. Marble is a metamorphic rock that forms when limestone is subjected to heat and pressure.
Metaphysical properties of blue calcite:
Blue calcite is a stone that is especially calming and soothing. Nearness of blue calcite is great for calming frayed nerves. Blue calcite in your environment can make you aware of needs for rest, which is the first step in helping you get the rest you need. Blue calcite is also an excellent stone for students. It helps retain lessons learned and amplifies learning.
Blue calcite also amplifies energy, particularly in the realms of communication and thought. Blue calcite is an excellent aid to communication. It fosters enlightened discussion, and eases communication between people with opposing views. It helps you express your views calmly and with tact. Blue calcite is also an enhancer of decision-making. It brings this quality to life through its ability to help you see more clearly what path will lead you to happiness. It also assists in remembering astral travel and channeling experiences.
In the physical realm, blue calcite is used for the throat, lungs, tonsillitis, thyroid, arthrits, joints, and high blood pressure.
