Sphalerite

TC100NV

Druse of complex equant crystals of Sphalerite, translucent, with good luster and a very deep toasted honey color, on matrix, with Calcite. From a find from the beginning of the second decade of this century in an abandoned mine whose Calcites and Barytes were already known, and which has now offered these specimens of Sphalerite of better quality than previous ones.

María Jesús Mine (Lobeto Mine), Sol Viejo, Cabanzón, Herrerías, Comarca Saja-Nansa, Cantabria Spain (2012-2013)

Specimen size: 8.1 x 6.4 x 4.4 cm

Main crystal size: 1.1 x 1 cm

€100 / US$103 / ¥14460 / AUD$150

Order

Quartz (variety jacinto de compostela)

TC90NC

Two Quartz crystals (Jacinto de Compostela variety) translucent, with bright luster and an intense red-orange color due to inclusions, on a massive gypsum matrix. A Spanish classic.

Domeño, Comarca Los Serranos, Valencia / València, Valencian Community / Comunitat Valenciana Spain (2011)

Specimen size: 5.7 x 3.6 x 4.1 cm

Main crystal size: 1.8 x 1 cm

€90 / US$93 / ¥13010 / AUD$130

Order

Pyromorphite

TC95NP

Group of Pyromorphite crystals, on matrix, with a prismatic habit, many of them doubly terminated, with good luster and a yellowish brown color. The specimen comes from an unexpected find in 1995 in an old lead mining area already exploited in Roman times and known for previous Pyromorphite finds, although with a different appearance from this specimen.

Resuperferolítica Claim, Cerro de la Canaleja, Santa Eufemia, Comarca Los Pedroches, Córdoba, Andalusia Spain (04/1995)

Specimen size: 3.1 x 2.8 x 2.4 cm

Main crystal size: 0.8 x 0.2 cm

€95 / US$98 / ¥13730 / AUD$140

Order

Pyromorphite

TC95NA

Very aerial group of Pyromorphite crystals with a prismatic habit, many of them doubly terminated, with good luster and a yellowish brown color. The specimen comes from an unexpected find in 1995 in an old lead mining area already worked in Roman times and known for previous Pyromorphite finds, although with a different appearance from this specimen.

Resuperferolítica Claim, Cerro de la Canaleja, Santa Eufemia, Comarca Los Pedroches, Córdoba, Andalusia Spain (04/1995)

Specimen size: 3.9 x 2.2 x 1.8 cm

Main crystal size: 1 x 0.3 cm

Order

Rodalquilarite with Jarosite

TC75NA

Small cavities filled with aggregates of Rodalquilarite crystals, on a Quartz matrix with Jarosite. The specimen comes from the type locality for the species resulting from a find in the now mythical Reef 340.

340 vein, Rodalquilar, Níjar, Comarca Metropolitana de Almería, Almería, Andalusia Spain (2012)

Specimen size: 2.1 x 1.9 x 0.9 cm

Type locality

€75 / US$77 / ¥10840 / AUD$110

Order

Chalcocite with Pyrite

TC80NE

Growth on matrix of very sharp Chalcocite crystals that form thick twins of hexagonal outline, with very well defined and brilliant faces and edges, covered with Pyrite microcrystals. These specimens have been analyzed and we will send a copy of the analysis to the buyer.

Las Cruces Mine, fase 6, levels 130-135, ↓175 m., Gerena-Guillena-Salteras, Comarca Sierra Norte, Seville, Andalusia Spain (09-11/2019)

Specimen size: 3.8 x 3.2 x 2.7 cm

Main crystal size: 0.5 x 0.5 cm

€80 / US$83 / ¥11560 / AUD$120

Order

Bornite after Chalcocite and with Calcite

TC220NZ

Group of very sharp Bornite pseudomorphs after Chalcocite crystals, as thick twins with a hexagonal outline, with very well defined faces and edges, brilliant and with intense metallic iridescence. The Bornite appears on a matrix with Calcite crystal coatings. These specimens have been analyzed and we will send a copy of the analysis to the buyer.

Las Cruces Mine, fase 6, levels 130-135, ↓175 m., Gerena-Guillena-Salteras, Comarca Sierra Norte, Seville, Andalusia Spain (01/2020)

Specimen size: 7.1 x 5.3 x 2.6 cm

Main crystal size: 0.6 x 0.3 cm

TC280NC

Growth of very sharp crystals of Chalcocite that form thick twins with a hexagonal outline, with very well defined and shiny faces and edges, on matrix, covered by Calcite crystals and Pyrite microcrystals. These specimens have been analyzed and we will send a copy of the analysis to the buyer.

Las Cruces Mine, Gerena-Guillena-Salteras, Comarca Sierra Norte, Seville, Andalusia Spain (01/2019)

€280 / US$290 / ¥40490 / AUD$430

Order

Titanite on Rutile after Ilmenite and with Microcline

TC180ET

A novelty at Sainte Marie-aux-Mines 2016. Platy Ilmenite crystals with irregular contours and completely pseudomorphed by Rutile, coated by very sharp Titanite crystals that are bright, with very well defined faces and edges, and with a very apparent pleochroism that shows a yellow color under led light but is greenish with daylight or neon light. Partially coated by Microcline crystals.
The process of replacement of Ilmenite by Rutile seems very similar to that of other localities with similar geological conditions (by example the Zambian Rutile) and it is due to hydrothermal processes at the site. We’ll send to the buyer a copy of the analyses done on the different species present in the samples.

Imilchil area, Anti-Atlas, Er Rachidia Province, Drâa-Tafilalet Region Morocco (2016)

Specimen size: 5.1 x 4 x 1.8 cm

Main crystal size: 1.6 x 1.4 cm
