Marcasite Vs Precious Opal Fracture
Fracture is an important parameter when you compare Marcasite and Precious Opal Physical Properties. It is necessary to understand the significance of these properties, before you compare Marcasite Vs Precious Opal 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 Marcasite is Gemstones (2009), Gemstones (2009), Uneven, UnevenArthur Thomas and UnevenArthur Thomas. Precious Opal fracture is Conchoidal, Conchoidal and Gemstones of the world (2001) More from other references.
Marcasite Vs Precious Opal Luster
A primary knowledge about Marcasite vs Precious Opal luster is useful in apparent identifications of these gemstones.

Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria.
