description: George B. Robbe (1884 to 1963) was a Michigan Tech alumnus and mining engineer who worked at the Quincy Mine and later at Bingham Canyon, Utah. He and his wife assembled a significant mineral collection that included both crystallized specimens and lapidary material. After his death, the collection was donated to the A. E. Seaman Mineral Museum in the late 1960s.
An outstanding miniature size native copper specimen from Michigan. Very sharp and aesthetically arranged crystals, the prominent crystal 1.5 cm in size forming a cluster with minor quartz. These show a very attractive tenorite patina. Previous label as seen at the end of the video comes from the A.E. Seaman Museum, ex George B Robbe collection.
Size: 5.0 x 2.5 x 2.5 cm (miniature)
