Aquamarine is a light blue or light greenish-blue variety of beryl, with darker stones being more expensive. Heat enhancement is often applied to enhance the blue color of aquamarines, but only clean pieces can be heated.

Black Opal Vs Aquamarine Fracture
Fracture is an important parameter when you compare Black Opal and Aquamarine Physical Properties. It is necessary to understand the significance of these properties, before you compare Black Opal Vs Aquamarine 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 Black Opal is ConchoidalArthur Thomas, ConchoidalArthur Thomas, Gemstones (2009) and Gemstones (2009).
Black Opal Vs Aquamarine Luster
A primary knowledge about Black Opal vs Aquamarine 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. Aquamarine, on other hand, exhibits Vitreous luster.
