Black Spinel 4x8mm Faceted Rondelle - 15-16 Inch 4mm Light Blue Stone Type: Rose QuartzSpinel is a hard vitreous magnesium aluminum oxide, and comes in a range of other colors, but those varieties are transparent. Black Spinel not only has the dark color, but it is opaque as well, rendering its black especially deep and mysterious. Sometimes called the "Black Prince's Ruby" for its role in the English crown.
