How do I identify Hedenbergite?

Hedenbergite can be identified by its hardness of 5.5 - 6.5 on the Mohs scale, brownish green color, Vitreous, Dull luster, Monoclinic crystal system. Look for these key characteristics when examining specimens.

What color is Hedenbergite?

Hedenbergite typically appears in brownish green, black. Color can vary depending on impurities and formation conditions.

How hard is Hedenbergite?

Hedenbergite has a hardness of 5.5 - 6.5 on the Mohs scale. This gives it moderate hardness.

What is Hedenbergite?

Hedenbergite is a rock forming mineral found primarily in metamorphic rocks. Its dark green to black color and can have a striking bright luster. Though not necessarily an uncommon mineral, good crystals are rare. Specimens that show good color and luster along with nice crystals are prized by mineral collectors.

Healing Properties

Hedenbergite works with the Base Root and Heart chakras to provide inner patience and determination. It connects the energy from the body with earth's energy to offer emotional healing. It may help to relieve feelings of sadness, anxiety or depression. It is believed to aid in matters of love and friendship, attracting others and promoting more joyful relationships.

Key Characteristics

Characteristics of Hedenbergite

Hedenbergite has a number of specific properties. Its hardness is usually between five and six with two cleavage plains and conchoidal fracture. Color varies between black, greenish black, and dark brown with a resinous luster. Hedenbergite is a part of a pyroxene solid solution chain consisting of diopside and augite, and is the iron rich end member. One of the best indicators that you have located hedenbergite is the radiating prisms with a monoclinic crystal system. Hedenbergite is found primarily in metamorphic rocks.

Formation of Hedenbergite

Hedenbergite can be found in skarns. A skarn is a metamorphic rock that is formed by the chemical alterations of the original minerals by hydrothermal causes. They are formed by large chemical reactions between adjacent lithologies. The Nickel Plate gold skarn deposit of the Hedley District in southern British Columbia is characterized by hedenbergitic pyroxene.

Composition of Hedenbergite

The pyroxene quadrilateral easily records the compositions of different pyroxene's contained in igneous rocks, such as diopside, hedenbergite, enstatite, ferrosilite. Hedenbergite is almost never found isolated. From the chemical formulas above, we can tell that the main differences in the compositions will be in terms of calcium, magnesium, and iron. D. H. Lindsley and J. L. Munoz (1969) did such an experiment in order to figure out exactly which combinations of temperature and pressure will cause particular minerals to combine. According to their experiment, at 1000 degrees with a pressure less than two kilobars the stable composition is a mixture of hedenbergite, olivine, and quartz. When the pressure moves to twenty kilobars, the composition moves towards the clinopyroxenes, which contains trace amounts of hedenbergite if any. For temperatures of 750 degrees Celsius, the compositions move from hedenbergite with olivine and quartz to ferrosilite with a greater amount of hedenbergite. If you combine the results of both of these sets of data, you can see that the stability of hedenbergite is more dependent on temperature as opposed to pressure.
