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.

Main crystal size: 0.4 × 0.3 cm = 0.2” × 0.1”

TF36H5: Crystals have a not so common habit because are very short and flattened prisms. The definition of their faces and edges is excellent as is the aerial distribution of crystals on the Marcasite matrix.
Baia Sprie Mine, Baia Mare, Maramures  Rumania (1984-1985)

Specimen size: 10.5 × 6.5 × 5.8 cm = 4.1” × 2.6” × 2.3”

Main crystal size: 1.6 × 1.4 cm = 0.6” × 0.6”

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 (10/2003)

Specimen size: 9 × 6.5 × 5.5 cm = 3.5” × 2.6” × 2.2”

Main crystal size: 3.5 × 2.7 cm = 1.4” × 1.1”

MH60J2: The crystals, which really are very flat rhombohedrons with extremely curved edges, are grouped in a floating rosette that seems divided in two parts due to black zoned inclusions of Boulangerite on one side.
Herja Mine, Herja, Maramures  Rumania (10/2003)

Specimen size: 3.7 × 3.5 × 2.5 cm = 1.5” × 1.4” × 1.0”

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 = 1.0” × 1.0” × 0.9”

Specimen size: 4.2 × 3 × 3.1 cm = 1.7” × 1.2” × 1.2”

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 = 1.1” × 0.9” × 0.9”

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 = 2.8” × 1.3” × 1.5”

E6RC9: More brilliant than others, this Galena from Turt displays very well with its separate crystals of galena on the clean brownish Siderite all on the matrix formed of massive Chalcopyrite-Sphalerite.

Specimen size: 8 × 5.5 × 4 cm = 3.1” × 2.2” × 1.6”

Main crystal size: 1.6 × 1.5 cm = 0.6” × 0.6”

Turt, Maramures  Rumania (2003)

Specimen size: 8.5 × 5.8 × 3.9 cm = 3.3” × 2.3” × 1.5”

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

Specimen size: 10.8 × 7 × 5.3 cm = 4.3” × 2.8” × 2.1”

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 = 2.8” × 1.7” × 1.5”
