Item Description
Bournonite specimens are very rare from Naica and this is an exceptionally aesthetic and fine thumbnail example from the Dick Heck Collection. Splendent, sharp, well-striated, metallic-gray, cogwheels are very jauntily set on the galena matrix. The cogwheels reach 8 mm. This is the first very fine Naica bournonite any of us have seen and it rivals Herodsfoot Mine specimens in quality. Valued at $200
