Please note: This item is an export restricted specimen and requires authorization from the CNSC to export outside of Canada. International customers please see the U & Th Mineral Ordering section link at the bottom of the main page for more information.

This stunning mineral pairing originates from the famous Musonoi Mine in the Democratic Republic of Congo, a site celebrated for producing some of the world’s finest secondary uranium minerals. The specimen features vibrant torbernite crystals intergrown with delicate cuprosklodowskite, forming a captivating interplay of bright green and subtle yellow-green hues. Each mineral displays excellent crystallization, with torbernite showing its characteristic tabular, layered structure, while the cuprosklodowskite presents a silky, fibrous texture that complements the more blocky torbernite formations.

Collectors will immediately notice the specimen’s remarkable contrast and color saturation, making it a striking display piece. The torbernite exhibits a translucent, glassy luster, while the cuprosklodowskite’s fibrous strands create visual depth and a sense of movement across the specimen. This combination not only highlights the beauty of secondary uranium mineralization but also offers insight into the complex geochemical processes at the Musonoi Mine, where copper-rich and uranium-rich fluids interacted over millennia to produce such remarkable crystallization.

This specimen, while visually captivating, is also highly radioactive and should be handled with care, ideally stored in a display case with limited handling. Beyond its aesthetic appeal, it serves as an educational example of rare uranium mineral paragenesis and is particularly sought after by collectors who value both scientific significance and vibrant mineral specimens. A piece like this is a true showcase of the Musonoi Mine’s mineralogical treasures.
