The color of ludlockite is interesting, but when combined with the metallic lustre to its fibrous crystals, the overall effect of a ludlockite specimen is unique and visually stunning. It looks like hair dipped in bronze and gelatin. This is a very rich, sturdy cluster of intergrown acicular crystals, perched on a minimal amount of ore matrix. A rare, display-sized, beautiful miniature specimen for this species normally available to collectors today only as micros or small pockets rather than with such large freestanding clusters such as this.
