These Black Rainbow Aura plated tumbles are a dramatic and eye-catching piece — a black tumbled base stone is treated with a metallic coating that creates vivid rainbow iridescence, shifting between electric blues, purples, and golds as the stone moves in the light. The result is something genuinely striking — a dark, mysterious base with an unexpected rainbow shimmer that makes these tumbles unlike anything else in a collection. These are wonderful for those who love the drama of Aura crystals with a more nocturnal, mysterious edge. At this accessible price they're a brilliant value for such a visually impactful stone.
