Bournonite is a highly sought-after sulfosalt originally found in Cornwall. These splendent, metallic-gray Bournonite crystals have a light iridescence and reach up to 1.2 cm across. They are richly scattered amongst milky Quartz crystals, and it all sits on a Sulfide matrix. Many of the Bournonites have the classic "cogwheel" crystal form. All around, a really nice Bournonite specimen at a very reasonable price, and superb for this particular locality.
