Bournonite

BournoniteA group of very well formed, sharp, semi lustrous, soft metallic grey colored tabular blades of Bournonite are intergrown to create this eye catching display specimen. The crystals are virtually damage free, save for two very small contacts on respective edges of the piece. For an added touch, the crystals are associated with micro grey Quartz. Great quality and rather aesthetic for the material. From a find in June of 2007. Specimen # BOL711B30

Specimen # BOL711B285

prismatic crystal of Vivianite which is associated with beautifully contrasting golden Childrenite aggregates

Specimen # AMBER51707

Definitely different from your typical Viloco specimens

This find produced record setting Andorite and Potosiite specimens but also produced some of the finest Zinkenites ever found from any world locality

and better than most I have seen from the mine

Specimen # BOL711B11

Subscribers to the Mineralogical Record know that an entire issue was dedicated to this unique and historic locality

particularly those from the famous Siglo XX mine

This piece is a good
