Fracture is an important parameter when you compare Indicolite Blue Tourmaline and Tortoiseshell Physical Properties. It is necessary to understand the significance of these properties, before you compare Indicolite Blue Tourmaline Vs Tortoiseshell 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.
Indicolite Blue Tourmaline Vs Tortoiseshell Luster
A primary knowledge about Indicolite Blue Tourmaline vs Tortoiseshell luster is useful in apparent identifications of these gemstones.
