Canada, Brazil, Madagascar, Mozambique, Russia, India, Pakistan, China, Sri Lanka, Color: yellow, green, pink or colorless, Hardness: 7.5, Refractive index: 1.57 1.59, Density: 2.67 2.75, Chemical composition: Be3Al2(SiO3)6, Crystal structure: hexagonal, Lustre: vitreous, Origins: Canada, Namibia, China. Among other varieties of beryl such as emerald, aquamarine or bixbite, beryl exists in different varieties such as: light yellow (heliodor), light green (vanadium beryl), light pink (morganite) or colorless (goshenite). Heat treatment could be applied to pink beryls to improve their color.

Beryl Vs Grossular Fracture
Fracture is an important parameter when you compare Beryl and Grossular Physical Properties. It is necessary to understand the significance of these properties, before you compare Beryl Vs Grossular 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 Beryl is Uneven, Conchoidal, Irregular, Gems and Brittle. Grossular fracture is Conchoidal, Uneven, ConchoidalArthur Thomas, Gemstones (2009) and Brittle.
Beryl Vs Grossular Luster
A primary knowledge about Beryl vs Grossular 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. Beryl exhibits Vitreous and Resinous luster. Grossular, on other hand, exhibits Greasy and Vitreous luster.
