Australian black spinel is a natural, untreated magnesium aluminum oxide gemstone featuring a deep, velvety black hue and high durability (8 on the Mohs scale).  Mined alluvial sapphire and ruby fields—such as the Central Queensland Gemfields and northern rivers in Tasmania (locally nicknamed "blackjack"), it is valued as an ethical, untreated alternative to black diamonds.
