Here we have big sharp and relatively isolated crystals of Arsenopyrite on matrix. The camera could not capture the super-bright metallic glimmer of this large specimen of sharp arsenopyrite - like shiny new nickels! The striations on the excellent defined crystal faces cause them to shimmer in the light. A super piece with only tiny imperfection, very hard to see. This specimen is way better in person,- an aesthetic, well crystallized ore specimen from Yaogangxian.
