Boldut Mine, Cavnic, Maramures  Rumania (±1970)

Specimen size: 6.5 × 5.8 × 3.7 cm

Main crystal size: 2 × 0.9 cm

TD56H7: The specimen is formed of groups of crystals of very pale Amethyst Quartz crystals growing from common points. The crystals have two main features. The three faces of the dominant rhombohedron are much larger than those of the other rhombohedron, and the crystals are thicker in the center of the prism so there is a curvature and tapering of the crystal. It is an excellent specimen for the locality.

Specimen size: 9.1 × 8 × 6 cm

Main crystal size: 6.2 × 1.3 cm

TV76H5: Crystals have very defined faces and edges and form very distinct interpenetrating twins. The sample is very esthetic due, especially, to the contrast between Chalcopyrite and the Quartz crystals with it.

It comes with an old label from the dealer C.F. Pech (Mineralien-Comtoir), Berlin.
Sacaramb (Nagyág), Apuseni Mountains, Alba County, Transylvania  Rumania (±1900)

Specimen size: 5 × 3.5 × 4.3 cm

Main crystal size: 1.1 × 0.8 cm

EJ62E9: A classic, but with features that make if different from other specimens from this locality. The prismatic crystals of Sylvanite, which are almost needles, are very brilliant and quite long. They are very well-defined and contrast well with the background of pale Rhodochrosite. We will give the purchaser a copy of the analysis of the Sylvanite, which we did because of its unusual appearance.

Specimen size: 10.5 × 8.5 × 5.6 cm

Specimen size: 8.4 × 6.6 × 2.9 cm

Main crystal size: 1.4 × 1.2 cm

TA63H5: The crystallization is very curious because the first impression is that crystals are cubes. A more attentive inspection indicates that they are rhombohedra but in the last phase of crystallization scalenohedron faces appeared to give the crystals their final form.
Boldut Mine, Cavnic, Maramures  Rumania (2000)

Specimen size: 6.7 × 5.3 × 3.5 cm

Main crystal size: 2 × 1.9 cm

Specimen size: 7 × 6.6 × 3.5 cm

Main crystal size: 3.6 × 3.4 cm

ME9F2: Growth of very flattened rhombohedra of Calcite on a single axis, so one can clearly see two zones, one clear with a hint of oxides and one darker due to inclusions of Boulangerite. The trigonal symmetry of the crystals is clear from the growth lines that create a very curious form.
Herja Mine, Herja, Maramures  Rumania (10/2003)

Specimen size: 2.6 × 2.5 × 2.4 cm

MD9F2: Growth of very flattened rhombohedra of Calcite on a single axis, so one can clearly see two zones, one clear with a hint of oxides and one almost black due to inclusions of Boulangerite. The trigonal symmetry of the crystals is clear from the growth lines that create a very curious form.
Herja Mine, Herja, Maramures  Rumania (10/2003)

Specimen size: 2.8 × 2.2 × 2.2 cm

MX63G8: The group is formed by cubes not so simple as it seems on a simple view. They form compact and numerous groups giving as a result slight curvatures on the faces and on the edges. The Pyrite is on a bed of little crystals of Siderite and a matrix of Sphalerite.
Turt, Maramures  Rumania

Specimen size: 7 × 3.4 × 3.8 cm

Turt, Satu Mare, Maramures  Rumania (1999)

Specimen size: 8 × 5.5 × 4 cm

Main crystal size: 1.6 × 1.5 cm

Turt, Maramures  Rumania (2003)

Specimen size: 8.5 × 5.8 × 3.9 cm

Main crystal size: 3.6 × 2.9 cm

E37JE8: The Chalcopyrite crystals in this sample are short. Faces and edges without curvature dominate the form, which is reinforced by the contrast with the matrix of groups of Quartz crystals and laminar Calcite crystals.

Specimen size: 14 × 10 × 3.5 cm

Main crystal size: 2 × 1.5 cm

Boldut Mine, Cavnic, Maramures  Rumania (04/2001)

Specimen size: 10.8 × 7 × 5.3 cm

T26DF6: The growth is very complex but the very brilliant crystals of Sphalerite have very well defined geometry, which is not that common. Especially esthetic given the contrast with the Chalcopyrite crystals.
Boldut Mine, Cavnic, Maramures  Rumania (04/2001)

Specimen size: 7.2 × 4.3 × 3.8 cm
