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.

Apatite Vs Chrysoberyl Fracture
Fracture is an important parameter when you compare Apatite and Chrysoberyl Physical Properties. It is necessary to understand the significance of these properties, before you compare Apatite 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 Apatite is Brittle, Conchoidal, Conchoidal, Conchoidal to uneven, ConchoidalArthur Thomas, Gemstones (2009) and Uneven. Chrysoberyl fracture is Brittle, Brittle, Conchoidal to uneven, ConchoidalWalter Schumann, Metallic, Metallic, Uneven and Uneven.
