Exceptional specimen featuring Native Silver dendrites with Calcite matrix!
Look at the incredible crystalline dendrites that climb the matrix on both the front and back!
Another smaller Silver "feather" can be seen near the lower right in the first photo. There's a slight
iridescence coloring the surface of the larger dendrites and several spinel-twin crystals can be seen poking
out between the dendrites on all sides. Without a doubt, this is the most impressive Silver I've seen from the
San Genaro Mine and one of the largest as well. Everything else I've encountered has been thumbnails or
very small miniatures. None have featured the impressive coverage and crystallization of this stunning piece.
From the San Genaro Mine, Castrovirreyna District, Castrovirreyna Province, Huancavelica Department, Peru.
Measures 6 cm by 4.5 cm by 4 cm in total size.

Superb cluster of Acanthite crystals with Pyrite on Calcite matrix!
Sharp crystals and an intense luster highlight this very aesthetic cluster. The Acanthite
crystals are all positioned vertically atop the Calcite which adds to the visual impact. The
largest crystal measures just shy of 2 cm in length. Some of the Acanthites display a slight
hoppering resulting from their quick transition from the higher temperature Argentite.
The specimen is in excellent condition with a back side stabilization along the right edge
to add structural support to the crystals in the area. The matrix is very well trimmed.
From the San Juan de Rayas Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico.
Measures 5.4 cm by 4.2 cm by 2.9 cm in total size.

Textbook specimen of Tri-State Galena, Sphalerite, and Calcite on Chert matrix!
This specimen could be pictured in a mineralogy book! The three crystal habits are so
perfect for the minerals featured and the way they are all sitting there together on the
same matrix is amazing. The Galenas are cubes, the Calcite is scalenohedral and doubly
terminated, and the Sphalerite is tetrahedral. In excellent condition with no visible contacts!
This specimen was in my personal cabinet for years and I'm pleased to offer it here.
From the Lead-Zine Mines, Tri-State Mining District, Cherokee County, Kansas.
Measures 8.3 cm by 5 cm by 4 cm in total size.

Price $3500
