The Mineral Cinnabar

This bright and vibrant mercury sulfide mineral comes in cinnamon to scarlet red color and looks attractive. Usually, crystals do not have a well defined shape. Collectors attribute a value to twinned crystals. Cinnabar displays a characteristic twinning, forming a penetrating twin which is ribbed with six ribs around the point, forming a pyramid. You can interpret it as two crystals (Sclahedral type) which have grown together, but going in opposite directions.

Derivation of Name
The cinnabar mineral derives its name from “kinnabari", a Greek word, most possibly applied by Theophrastus to numerous distinct materials. At times, in Latin this was known “as minium," meaning also "red cinnamon." Now both the terms refer particularly to lead tetroxide.

Occurrence
Cinnabar is usually found as a cavity filling mineral at places that lately experienced volcanic activity. You can also find Cinnabar near hot springs (alkaline). Epithermal aqueous solutions (ascending) deposit the Cinnabar far away from their hot volcanic origins. It is coupled with native Barite, Chalcedony, Calcite, Mercury, Dolomite, Realgar, Stibnite, Pyrite, Opal, Marcasite and Quartz.

Gemology

Cinnabar is known for its powerful metaphysical properties. It is also a famous stone for the creation of wealth and is referred to as the 'Merchants Stone'. The energy transmitted by this stone may bring in more wealth for your business. It is also known as a stone that helps to begin your spiritual vision.

Source
The mineral, Cinnabar, occurs in areas where mercury is obtained in prominent places like New Almaden (California); Puerto Princesa in the Philippines; Almaden (Spain); St. John’s Mine and Hastings Mine, Ne Idria (California), Vallejo, California; Idrija (Slovenia); Giza in Egypt; Landsberg adjacent to Obermoschel situated in the Palatinate; Ripa, situated at the foot of the Apuan Alps. It also occurs in the Mount Amiata (Tuscany); Huancavelica (Peru); the mountain Avala (Serbia); Arkansas; the Guizhou province, located in China and Terlingua (Texas), where pure crystals are found.

Mineralogy
Cinnabar rarely occurs as crystals having a non-metallic adamantine luster. It has a rhombohedral bravais lattice, and falls in the category of the hexagonal crystal system, trigonal division. Generally, the crystals grow in a massive habit though they may be twinned at times.

Color
It comes with a bright scarlet or cinnamon red to a brick red.
