Gray Spinel 7 x 5mm Oval Faceted Gemstone

Gray spinel, a transparent variety of vitreous magnesium aluminum oxide, is relatively hard (7.5–8 on the Mohs hardness scale) and presents a true silvery to medium gray color (not a desaturated black or blue). When faceted, the gemstone offers an unexpected refractive brilliance. According to a legend, gray spinel clarifies thoughts, stimulates creativity and emits a protective energy that connects its wearer to the center of the earth. Named for its spiky crystal structure from the Latin "spina" (meaning "thorn"), spinel is a vitreous magnesium aluminum oxide. Hard, durable and occurring naturally in a range of transparent colors, spinel is a versatile gemstone for all forms of jewelry. The oval cut is an even, symmetrical shape but elongated. The arrangement of its facets is similar to that of a round brilliant, designed to maximize light and color.
