AF11AM3: Group of disphenoidal crystals (pseudotetrahedral) of Chalcopyrite, with sharp crystal forms. On a Magnetite matrix with octahedral crystals of Magnetite.
French Creek Mines, St. Peters, Warwick Township, Chester County, Pennsylvania  USA

Specimen size: 4.4 × 3.2 × 2.3 cm = 1.73” × 1.26” × 0.91”

Main crystal size: 1.2 × 0.7 cm = 0.47” × 0.28”

TR16AM3: Very aerial group of lamellar Gold crystals (variety electrum), some of them with very well marked skeletal growths and a little matrix at the back. The specimen comes from a relatively recent find in a known gold zone.
Specimens from this find were analyzed and we will send a copy of the analysis to the buyer.

Specimen size: 2.9 × 2.5 × 1 cm = 1.14” × 0.98” × 0.39”

TD88AM3: A novelty at Tucson 2020. Group of Olivenite crystals on matrix, one of them clearly dominant and very aerial and sharp, flattened, with very well defined faces and edges and perfect terminations. With good luster and a very deep olive-green color. As on so many other occasions in Milpillas, among the best for the species.

MR27AM3: Group of large Chalcopyrite crystals with the typical curvatures seen in Panasqueira specimens, very aerial, lustrous, and on matrix. With sharp and lustrous Arsenopyrite crystals and small coatings of lenticular Siderite crystals. As a whole, it is a very high level piece both for its perfection and for the quality of the Chalcopyrite crystals, a species that in this mine does not usually yield very good specimens.

Main crystal size: 1.5 × 1.1 cm = 0.59” × 0.43”

HM87AM3: Sulphur crystals with a dipyramidal habit, very sharp crystal forms, and which retain, despite time, an excellent luster and color. On matrix with globular coatings of small Calcite crystals. A Sicilian classic from an old collection.
Caltanissetta Province, Sicily  Italy

Specimen size: 11.4 × 9.3 × 9.2 cm = 4.49” × 3.66” × 3.62”

Main crystal size: 1.7 × 1.5 cm = 0.67” × 0.59”

SM99AM3: Fine coralloid growths of Aragonite with stalactitic forms, pale blue due to the copper content. The specimen is from the Francesco S. Stoppani collection (number 0515), whose label we will send to the buyer together with other old labels from the Rosenkranz and N. Stotzel collections. As with many of the specimens in this collection, this one is of high quality for the locality, a classic of Italian mineralogy.
