An excellent and colorful Franklinite combination specimen from the historic Trotter Mine at Franklin, New Jersey, circa late 1800s, with a startlingly sharp textbook crystal of franklinite. The Trotter Mine surface and underground workings represent some of the oldest workings in the Franklin area by the New Jersey Zinc Corporation in the late 1800s to early 1900s. This great piece consists of a single, black, submetallic franklinite crystal perched on a coarse-grained matrix of white calcite and pink rhodonite, both have some crystal faces. Although the piece is repaired with the franklinite being restored onto the matrix, the franklinite crystal is very unusual for the franklin area with its perfect dodecahedral crystal form! The diamond-shaped faces are well-formed and edges are sharp. There is some fine-grained franklinite disseminated in the matrix and the calcite glows a bright red in short-wave UV. Recently from the George Loud collection and, we believe, a rare and refined example of this species.
