Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Sapphire is Gems, Sixth Edition (2006), Uneven and Uneven. Howlite fracture is Brittle, Conchoidal, Gemstones (2009), Gemstones (2009), UnevenArthur Thomas and UnevenArthur Thomas.

Sapphire Vs Howlite Luster

A primary knowledge about Sapphire vs Howlite 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. Sapphire exhibits Adamantine, Adamantine, Vitreous and Vitreous luster. Howlite, on other hand, exhibits Vitreous luster.
