Stibnite, Wolfsberg, Stolberg, Harz, Saxony-Anhalt, Germany Attractive cluster of acicular, iridescent needles of stibnite from the Wolfsberg locality in Germany. This blocky piece is composed of what seems like thousands of slender stibnite crystals. The luster on the faces is quite high, and the flashes of iridescence add a lot of visual interest with its blues, greens, and purples accenting the silver. https://www.irocks.com/minerals/specimen/47303
