This is a really intricate and detailed arborescent Silver specimen composed of numerous spinel-twinned crystals circling around and through a knot of white Calcite in the center, from the historic Batopilas Mine of Mexico. One side has elongate spires of spinel twins with dendritic growths off of them compared to the other side where the arborescent crystals are shorter and somewhat more dense. The knot of white Calcite adds color and aesthetics. It really is a well balanced specimen with almost equal amounts of arborescent Silver on either side of the Calcite that is largely internal to the piece, and it has of course been etched out to reveal the Silver better. This piece has great contrast and good aesthetics. Mexican Silvers of this quality are scarcely available these days. This locality produced in bursts, with specimens of different styles coming out circa 1900, early 1900s, the 1960s, and again in the 1980s. This is from the 1960s finds, according to Dr. Peter Megaw who examined it for us. 123 grams. Complete, 3-dimensional and without damage all around! Additionally, aside from the piece itself, it has great provenance. We obtained this from the family of Bill Panczner, author of the respected book Minerals of Mexico, and from his personal collection.
