    CHALCOCITE
    Bristol Copper Mine, Bristol, Hartford County, Connecticut, USA

    As the population of the United States has grown, many mines and quarries that were formerly "in the sticks" have been incorporated into the expanding villages, towns and cities that characterize modern America. A prime example of that phenomenon is the Bristol Copper Mine of the Connecticut Valley that tapped some very rich Copper ore during its heyday. This mine was the richest of the district and its production powered the local industries centered about Waterbury, producing copper and brass articles for daily commerce. Oddly enough, it was mismanagement, not depletion, that closed this mine. Reportedly, there are still many tons of high to low-grade ore left in the mine. The Bristol Mine is well known among collectors for the size and perfection of the Chalcocite specimens saved from the smelter by miners toiling in its depths. This classic example shows the complex habit and striated faces that are characteristic of this mine. Luster is also correct, alternating from iridescently lustrous to matte on various crystal faces. It is quite large and remarkably pristine for Chalcocite from Bristol and the accompanying labels indicate that it resided for a time in the collection of Richard Barstow, an important dealer/collector, now deceased, from Cornwall, England. This is significant in that Cornwall is the other premier locality for this mineral. As is normal for Bristol material, there is no matrix and the specimen appears to have formed as a "floater": a specimen with no obvious point of attachment to a cavity wall. There are two accession number on the back-side, one "155B" is identical to the Barstow label and the other that appears to be "1588", probably just a typo and a variation on the former one.
    Overall measurements: 2.5 x 2 x 1.25 inches (6.4 x 5.1 x 3.2 cm).

    Provenance: Attard Minerals, ex. Richard Barstow Collection [Hoppel # D0416]
