Stone Medicine - Calciteby Alannah Hudis on 06/09/17
"Calcite is the one of the most common minerals. It occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth's rocks.
Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series. All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in transparent rhombohedrons." (http://www.minerals.net/mineral/calcite.aspx)Calcite "has a defining Mohs hardness of 3, a specific gravity of 2.71, and its luster is vitreous in crystallized varieties. Color is white or none, though shades of gray, red, orange, yellow, green, blue, violet, brown, or even black can occur when the mineral is charged with impurities.
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." (https://en.wikipedia.org/wiki/Calcite)
As can be seen in the above photos, calcite comes in a dizzying array of colors, shapes and luster. As a group, they have commonalities, but also have particularities of medicine depending on color and type. Calcites are lovely stones to have in a healing collection. They have a cheery aspect and are easily communicative. As a group they are beneficial for maintaining mineral balance in the body and are especially good for the teeth, bones, muscles and tendons.
These stones prefer to be refreshed in moonlight, direct sunlight may fade their colors and they are not fond of getting excessively wet. Communally they correspond to the elements of air and water vapor.
Individual correspondences of some of the colors of calcite are:
Blue: The moon: moon phases/moon magic; watery systems/tidal volume in the body; evening/nighttime
Green: Muscles; heart & lungs; daytime; growth; garden;
Orange: Sunshine; stomach; nourishment
Yellow: Muscle & tendon healing; urinary tract; kidney function; optimism
Optical: White light; physical vision; scrying
