Silvery colored cluster of Gratonite, a rare lead arsenic sulfide. Well formed bright crystals spraying out in all directions. This is an uncommon matrix specimen (most are loose clusters without matrix). There are some missing crystals that don't really detract from the overall aesthetic of this cute thumbnail.
