in gneisses or granulates places:Excellent Augite crystals are found in the Italian volcanoes of Vesuvius, Stromboli, Etna, and Lazio. Good crystals also come from the Bushfield Complex, Transvaal, South Africa; Auvergne, France; and Eifel, Germany. In the U.S., large crystals are found in upstate New York in the St. Lawrence area (Balmat, Pitcairn, DeKalb, Diana, etc.) Crystals similar to those are also found in Canada in Renfrew Co.
Another famous area for Augite crystals are the Ramapo Mountains, Orange and Rockland Counties, New York (Hogencamp Mine, Brooks Hollow, and Iona Island). Augite is also found in Franklin, Sussex Co., New Jersey; the Trail Creek area, Grand Co., Colorado; the Stillwater Complex, Montana; and Cedar Butte, near Tillamook, Tillamook Co., Oregon.

Augite is primarily used as a minor gemstone when it forms as part of rocks like basalt. It is also utilized in the building and construction industry as a source of crushed stone or aggregate due to its hardness and durability. Additionally, augite's presence in igneous rock formations can provide valuable insights into the geological history and formation of the Earth's crust.
The order of hardness from softest to hardest for the mentioned minerals is as follows: cinnabar, emerald, augite, sapphire, magnetite.
The cost of augite can vary depending on factors such as size, quality, and origin. On average, a small specimen of augite can be purchased for around $5 to $20, while larger and higher-quality specimens can cost more, reaching hundreds or even thousands of dollars. It's recommended to check with mineral dealers or online retailers for specific pricing.
Augite typically forms elongated prismatic crystals with a square or octagonal cross-section. These crystals may exhibit cleavage along two directions forming angles of nearly 90 degrees.

The specific gravity of augite, a common mineral in the pyroxene group, ranges from approximately 3.2 to 3.6. This specific gravity measurement can help in distinguishing augite from other minerals when analyzing rock samples.

Augite is commonly found in igneous rocks such as basalt and gabbro. Mining for augite specifically is not common due to its presence in these types of rocks. It is typically extracted as a by-product during the mining of other minerals like copper, nickel, and platinum.
Augite is a type of pyroxene. It is a common mafic-intermediate igneous mineral, but can also be found in some metamorphic rocks.
The value of augite can vary depending on the quality, size, and location where it is found. Augite is a common mineral and is not typically valuable in terms of money, unless it is of exceptional quality or size for collectors or researchers. In general, the value of augite is more commonly based on its scientific or educational significance rather than its monetary worth.
