Arsenopyrite

“Orthohombric. Usually in tabular diamond-shaped crystals, formed by a short prism terminated by low brachydomes. The brachydomes are usually striated parallel to the brachy-axis. Twinned at times, giving stellate groups; the different individuals of the twin groups being distinguished from each other by the direction of the striations upon them.” — Ford, 1912
