A classic, old time example of proustite from Germany!!! This specimen consists of a complex, twinned crystal of proustite with
a small amount of matrix in association!!! The interpenetrant crystals have highly complex features that make it difficult
to capture in the pics, however it is much more complete and sharp than it appears in the pics!!! This complexly twinned
crystal is terminated and displays terrifically all around!!! The specimen is much more sharp and complete than the pics show!!!
The crystal has a deep, dark red color and glassy luster!!! Although the old label describes it as a proustite crystal, it
is superficially more characteristic of pyrargyrite crystals from this locality!!! Classic old time material!!!
This specimen is from the A.E. Seaman Mineral Museum and retains an old label with L.L. Hubbard Collection (1849-1933) notation (the specimen also
has an affixed museum catalogue number on the bottom as well)!!!

"Lucius L. Hubbard (1849-1933)
Hubbard was a life-long mineral collector, and he also took time off to study mineralogy at the Universities of Heidelberg and Bonn beginning in 1883. After receiving his PhD in Bonn in 1886 he joined the staff of the Michigan Geological Survey and the Michigan College of Mines in 1890. In 1893 he left to become Michigan State Geologist, a post he held until 1899, when he resigned to head geological exploration activities for the Copper Range Company. He discovered the southern extension of the Baltic lode, the last big native copper deposit to be found in the district; it became the Champion mine, where Hubbard later became general manager. He served as a member of the Board of Control of the Michigan College of Mines, and as a Regent of the University of Michigan, from 1910 until his death in Eagle Harbor, Michigan on August 3, 1933.
Despite being partially color-blind, Hubbard built an immense, first-class personal mineral collection, which he
donated to the Michigan College of Mines (today Michigan Technological University)."
The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
