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.
R.J. Roberts lode, Willow Creek District, Pershing County, Nevada  USA (2015)

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.
Milpillas Mine, level 992, Cuitaca, Municipio Santa Cruz, Sonora  Mexico (11-12/2019)

Specimen size: 2.2 × 1.4 × 0.8 cm = 0.87” × 0.55” × 0.31”

Main crystal size: 1.1 × 0.3 cm = 0.43” × 0.12”

EK69AM3: Group of Azurite crystals with very sharp crystal forms and a very vivid color, with Malachite pseudomorphs after Cuprite crystals with the dominant forms of octahedron and dodecahedron. A French classic.
Chessy-les-Mines, Les Bois d'Oingt, Villefranche-sur-Saône, Rhône, Auvergne-Rhône-Alpes  France

Specimen size: 5.3 × 3.4 × 3.3 cm = 2.09” × 1.34” × 1.30”

Main crystal size: 1.5 × 1.3 cm = 0.59” × 0.51”

EE67AM3: Druse of complex twinned Sphalerite crystals with sharp crystal forms, lustrous, and yellow in color. Transparent under strong light. On matrix, with cubo-octahedral Galena crystals. The back of the piece has been partially sawn.
Madan mining area, Rhodope Mountains, Smolyan Oblast  Bulgaria

Specimen size: 9.4 × 6.4 × 4 cm = 3.70” × 2.52” × 1.57”

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

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.

Specimen size: 17.3 × 8.6 × 11 cm = 6.81” × 3.39” × 4.33”

EH26AM3: Group of Calcite crystals with a very sharp pseudohexagonal outline, some of them doubly terminated, completely covered by a second generation of small scalenohedral crystals. On matrix, with centered growths of acicular white Prehnite crystals.
Due to its genetic complexity the specimen has been analyzed and we will send a copy of the analysis to the buyer.
Jebel Masker, Imilchil area, Tounfit, Khénifra Province, Beni Mellal-Khenifra Region  Morocco (2019)

Specimen size: 8.8 × 6.4 × 7.1 cm = 3.46” × 2.52” × 2.80”

EL96AM3: From a 2019 discovery at a greater depth than usual in the Coud'a area. With polycrystalline groups and parallel growths of Vanadinite crystals with a thick tabular habit, on matrix, many of them doubly terminated and with hopper growths. Very lustrous and with a very vivid and uniform magenta-red color, less intense on the back. High quality.
Coud'a, Mibladen mining district, Mibladen, Midelt, Midelt Province, Drâa-Tafilalet Region  Morocco (04-05/2019)
