Origin
Kazakhstan
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, Brazil, USA, Sri Lanka, 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

Kurnakovite Vs Andalusite Fracture
Fracture is an important parameter when you compare Kurnakovite and Andalusite Physical Properties. It is necessary to understand the significance of these properties, before you compare Kurnakovite 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. Fracture observed in Kurnakovite is Brittle and Conchoidal. Andalusite fracture is Gemstones (2009), Splintery, Subconchoidal, Subconchoidal, Uneven, Uneven and UnevenArthur Thomas.
Kurnakovite Vs Andalusite Luster
A primary knowledge about Kurnakovite 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. Kurnakovite exhibits Vitreous luster. Andalusite, on other hand, exhibits Greasy and Vitreous luster.
