Bluish stones are most valuable. Prices for chrysoberyls grow rapidly with weight, and clean stones bigger than 15 cts are rare and therefore an excellent investment.

Chrysoberyl Vs Dravite Fracture
Fracture is an important parameter when you compare Chrysoberyl and Dravite Physical Properties. It is necessary to understand the significance of these properties, before you compare Chrysoberyl Vs Dravite 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 Chrysoberyl is Brittle, Brittle, Conchoidal to uneven, ConchoidalWalter Schumann, Metallic, Metallic, Uneven and Uneven. Dravite fracture is Brittle, Conchoidal, ConchoidalAnthony et al, Handbook of mineralogy (2001), Irregular, Uneven and Uneven.
Chrysoberyl Vs Dravite Luster
A primary knowledge about Chrysoberyl vs Dravite 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. Chrysoberyl exhibits Vitreous luster. Dravite, on other hand, exhibits Vitreous luster.
