Melonite is an uncommon nickel telluride. This fine thumbnail from the Cresson Mine at Cripple Creek features at rich plate of melonite pseudomorphing calaverite (gold telluride) crystals and is very nicely accented by a small rosette of quartz crystals. The melonite rests on a thin crust of tiny quartz crystals. Highly representative of the species and historic locale. Probably very old material, too.
