Beautifully burnished, curved and curled, silver wire is very aesthetically set on a matrix plate of light gray calcite and accented with iridescent bornite
Classic sample of native silver in crystallized branches, accompanied by sulfides such as arsenopyrite, pyrite, and tennantite. Hundreds of small quartz crystals cover the matrix like a layer.
Fine sculptural sphalerite combination specimens are uncommon from the San Antonio Mine at Santa Eulalia. Typical calcite crystals can also be seen in the sample.
These pseudomorphs are a Mexican classic. The material is instantly recognizable, with the gentle yellow color stibiconite that has replaced the original stibnite crystal.
Very aesthetic cluster of transparent apophyllite crystals with a doubly-terminated bow-tie formation of orange-pink stilbite crystals. Very clean. No damage.
A large number of copper sulfides are present in this sample. Mainly it is composed of tennantite, but there are also crystals of chalcocite, bornite and massive chalcopyrite. Crystallized calcite and capillary asbestos, all on andesite matrix.
