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.

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