Taxco de Alercon, Municipio de Taxco
3.6 x 2.8 x 1.4 CM (miniature)
Dark Silver-Black mass of crystallized Pyrargyrite on a chard of matrix. Strong light shows distinctive Ruby red color on most areas. There are areas of "meltedlook" masses mixed with very sharp small crystals in textbook form. Fascinating under good magnification, the specimen is complex and has several habits present. An older piece from Taxco in great condition. We do not have an exact mine attribution, it is common from this region especially with older pieces that many small mines and prospects send ore and specimens together for processing and sale.
A bright, sparkling old Mexican Rhodo with Scalenohedra that are covered by clear tiny quartz crystals that add a bright luster. The rich pink color of the Rhodocrosite is clearly seen through the druzy Quartz. Some typical sulfides make up the rest of the matrix, the dark colors adding contrast. In very good condition, a few old breaks are noted and seem at least partly revealed, however as seen this is still a very fine display piece.
Amethyst - zoned crystals
Amatitlan, Municipio de Zumpango del Rio
4.1 x 2.1 x 1.9 CM (miniature)
pre Tucson 2015 update
An attractive miniature showing the distinctive habit of Guerrero Amethyst. This shows both the classic esthetic arrangement and shape of crystals with the zoning that sets these apart from all other Amethyst. In good condition, there is some chipping to be found with magnification so this is not for the perfectionist. Far better than average and much more affordable than larger pieces. Vintage about 1955.
A very good, older specimen with the distinctive form that makes the Guerrero Amethyst world famous. From the "golden years" in the 1930's vintage mining, This is a single crystal with a few side crystals attached presenting the "fat belly" form with good (slightly better than average) color. The phantoms are also quite distinct and are more impressive in person reaching a deep grape purple color at the core. Some typical minor bruises are seen in the photos, and some side crystals have chipping, but these can be hidden by rotating the piece. I would rate this specimen as well above average for color, size and form but not a "super-top" piece (which in this size can be a 20-30K specimen!). A good value for a fine addition for any Mexican collection or quartz suite
