Bisbee was one of those mining districts that everyone still talks about to this day, even almost a century after its mines closed down and all of its production stopped. This is partly thanks to the abundance of very nice specimens on the mineral market brought on by the rampant High grading the miners took part in, something I personally don’t feel like complaining about, and also thanks to the remarkable quality for multiple copper carbonate species unlike anything that had been seen before at that time.
This cabinet is one of such specimens. Having been nicely preserved for its age and fragility, it features a triangular three dimensional goethite and limonite gossan matrix that appears richly covered by a bloom of finely crystallized navy to cobalt blue azurite rosettes, both kinds giving very strong electric blue internal reflections under moderate lighting, with the biggest one being ~0,5cm. Depending on the area of the specimen, these aggregates appear with a nice glassy luster typical of the species or with a more velvety finish to them, almost chatoyant that, under the light, looks quite mesmerizing.
As far as damage goes, there are some partial crystals on the periphery and a little consolidation on the crack that can be seen on the left of the specimen’s photos, but like I said before, it is just excellent for its age and definitely not an ugly rock by any means.
