Apophyllite - Pink
Guanajuato, Municipio de Guanajuato
8.7 x 6.8 x 4.6 CM (cabinet)
A fine crust of Apophyllite crystals with a light pink color and glassy luster. An older piece from Guanajuato with the typical Quartz matrix having amethyst zoning. From the Stanek collection (Brno, Czech republic) we do not see many Guanajuato specimens available, most Mexican pinks are from Zacatecas or Charcas but these were found long before those later finds. In super fine condition.
Acanthite and Polybasite on Quartz
San Juan de Rayas Mine, Municipio de Guanajuato
5.7 x 4.4 x 2.3 CM (cabinet)
A melted look sculpture of Acanthite crystals on Quartz also holds a few small Polybasite crystals in sharp hexagons. Choice older piece from the San Juan de Reyas mine in Guanajuato. In excellent condition as seen and with a nice dark metallic patina. Under 20 X magnification I can see glints of blood red color that indicates at least a tiny bit of Ruby Silver (Pyrargryite) is also present but very small.
A classic and fine old specimen of the Adularia variety Valencianite. Ex Harvard University, Ken Hollman and Terry Szenics collections. From the Valenciana Mine(Guanajuato, Mexico) this has sizable crystals to 2.7 CM,and is in perfect undamaged condition. A dusting of small clear Quartz crystals and a few micro Sulfides ads some character as well.

A well formed thumbnail of complex Acanthite crystals. These show modified cube forms and "melted" look hoppered crystals. A nice dark silver patina and good luster give this a nice presence. A classic Mexican specimen.
Calcite on Quartz (amethyst)
Mina Peregrina, Guanajuato
8.4 x 6.4 x 4.1 CM (cabinet)
Bright glassy clear crystals of light pink-violet Calcite perched on a contrasting amethyst matrix. Classic material from Guanajuato, this is quite eyecatching. In excellent condition, there is a single clean repair that is super hard to find, that needs to be mentioned. This keeps the price low yet this displays like it cost far more.
This thumbnail Acanthite shows textbook forms and habits in sharp, undamaged crystals that have very good luster. A modern classic locale, the San Juan de Reyes mine has been the source for some outstanding silver minerals, this one is an excellent example.
