HEMATITE and QUARTZ 2.75″ X 3″

$30.00

Hematite from the Greek haimatites meaning “blood like” crystallizes in the hexagonal system, an ink black often with silver luster.

The mother of the quartz family which is comprised of silicon dioxide which is the second most abundant mineral in the Earth’s continental crust. Its a transparent rock crystal which holds all the color rays of the rainbow. Also referred to as “Rock Crystal”, the transparent, colorless variety of macrocrystalline quartz, occurs as well-developed crystals on plates and in geodes and is among the most widely collected of all minerals.

HEMATITE

 

HISTORY, NAME, LOCALITIES:  Hematite served as the earliest red pigment.  Mineralogists recognized it as a species in the late 1700s.  Its name comes from the Greek haimatites, meaning “blood-like,” alluding to the red color of its earthy forms.  Notable collecting localities are found in Morocco, England, Pakistan, Switzerland, China, and the United States (Michigan, Minnesota, Wisconsin, Utah, Georgia, New York).

 

MINERALOGY, PROPERTIES, OCCURRENCE: Hematite [iron oxide, Fe2O3], pronounced HEE-muh-tite, is the most common iron-containing mineral.  It crystallizes in the hexagonal system (trigonal subsystem) in massive, botryoidal, compact, and earthy forms, and less frequently as thick-to-thin, tabular crystals.  It has a Mohs hardness of 5.5-6.5, no cleavage, a diagnostic deep-red streak, and a specific gravity of 4.9-5.3.  Massive and compact forms are steel-gray-to-black in color and have a metallic luster; earthy forms are cherry-red to reddish-brown with a dull luster. Hematite is found in sedimentary deposits, carbonatites, disseminated replacement deposits, regional metamorphic rocks, and hydrothermal veins.

 

QUARTZ (var. ROCK CRYSTAL)

 

HISTORY, NAME, LOCALITIES: Rock crystal, which is common and occurs worldwide, has been collected since prehistory.  Notable collecting localities are found in India, Brazil, Germany, Peru, Bolivia, Namibia, Russia, and the United States (Arkansas, Colorado, Maine, Connecticut, Virginia).

 

MINERALOGY, PROPERTIES, OCCURRENCE: Rock crystal is the transparent, colorless variety of macrocrystalline quartz [silicon dioxide, SiO2).  The word “quartz” is believed to have originated with the Slavic kwardy, meaning “hard,” in allusion to its substantial hardness.  It crystallizes in the hexagonal system and occurs mainly in hydrothermal veins, granite pegmatites, and as geode linings as short-to-long, horizontally striated, hexagonal, prismatic crystals with pyramidal terminations and distinctive, water-clear transparency.  It has a Mohs hardness of 7.0, a conchoidal fracture, vitreous luster, and specific gravity of 2.65.

 

METAPHYSICAL PROPERTIES, LORE, USES: Rock crystal has since antiquity been one of the most widely collected of all minerals.  It has served as a gemstone and ornamental stone in many cultures.  Until quartz was synthesized in the 1960s, rock crystal was vital to electronic frequency controls, filters, and timing devices. Modern metaphysical practitioners call rock crystal the “universal crystal” because of its numerous abilities to sharpen insight, enhance spiritual development, improve concentration, refine focus, and energize the mind.

 

COLLECTORS’ INFORMATION: Rock crystal is widely collected for its brilliant transparency, superb hexagonal crystal development, and frequent occurrence on large plates and in geodes to make interesting display pieces.

 

 

METAPHYSICAL PROPERTIES, LORE, USES: Medieval physicians used hematite to treat circulatory, heart, and kidney disorders.  Modern metaphysicists believe that hematite enhances energy, vitality, memory, and intellect; helps to tolerate stress; and aids overall healing.  Hematite is the official state mineral of Alabama.  As the primary ore of iron, hematite has yielded about 85 percent of all the iron ever mined.  A silvery-gray, compact, crystalline form, called “specular hematite,” is fashioned into decorative objects and cabochons.

 

COLLECTORS’ INFORMATION: The botryoidal, and crystalline forms of hematite are collected for their steel-gray color; bright metallic luster, and distinctive shapes.
