A sharp, gorgeous crystal of this very rare occurrence of an already rare silver sulfide mineral. These crystals are known for sharp edges and colorful iridescence on surfaces. These were found only a few times, and this one likely came from the "big find" which actually only filled a coffee can - Joe Weinholtzner's storied 1977 find at the remote Husky mine. No more have been found since, and there is little hope as well. They remain amazing old classics of silver species.
