Origin
Austria
Spain, Brazil, USA, Sri Lanka, Burma, Color: strongly pleochroic, reddish brown, pink / yellowish green, Hardness: 7 7.5, Refractive index: 1.63 1.65, Density: 3.13 3.21, Chemical composition: Al2SiO5, Crystal structure: orthorhombic, Lustre: vitreous, greasy, Origins: Spain, Burma. Discovered in Andalusia (Spain), the andalusite stone is relatively rare, with big crystals over 10 ct. especially rare. Due to its remarkable pleochroism effect, the stone is highly valued by collectors., brown

Bronzite Vs Andalusite Fracture
Fracture is an important parameter when you compare Bronzite and Andalusite Physical Properties. It is necessary to understand the significance of these properties, before you compare Bronzite Vs Andalusite fracture. Whenever a gemstone chip breaks, it leaves a characteristic line along its breakage. Such lines are known as fracture and are used to identify the gemstones in their initial stages of production when they are in the form of rough minerals. Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Andalusite fracture is Uneven, Subconchoidal, Splintery, UnevenArthur Thomas and Gemstones (2009).
Bronzite Vs Andalusite Luster
A primary knowledge about Bronzite vs Andalusite luster is useful in apparent identifications of these gemstones. Luster is the measure of light that gets reflected when incident on a finished cut gemstone. There are two major types of lusters: Silky and Adamantine. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Andalusite, on other hand, exhibits Vitreous and Greasy luster.
