Poldervaartite Vs Watermelon Tourmaline Fracture
Fracture is an important parameter when you compare Poldervaartite and Watermelon Tourmaline Physical Properties. It is necessary to understand the significance of these properties, before you compare Poldervaartite Vs Watermelon Tourmaline 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 Poldervaartite is Handbook of mineralogy (2001). Watermelon Tourmaline fracture is Conchoidal, Conchoidal, Irregular, Management Team (2012), Uneven and Uneven.
Poldervaartite Vs Watermelon Tourmaline Luster
A primary knowledge about Poldervaartite vs Watermelon Tourmaline 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. Poldervaartite exhibits Vitreous luster. Watermelon Tourmaline, on other hand, exhibits Vitreous luster.
