9WP-CXTQuartz

Rio Maggiore, Porretta quartz sites, Porretta Terme, Alto Reno Terme, Reno Valley, Bologna Province, Emilia-Romagna, Italy

Dimensions: 56 mm x 48 mm

Marco Bertolani Collection
Very beautiful skeletal quartz collected in the valley of Rio Maggiore, close to Porretta Terme. The specimen measuring 56 x 48 mm, shows a beautiful colour saturation connected to the reddish oxides covering the crystal faces (probably Fe or Mn oxides). Just a few clefts in the area of Porretta Terme contain crystals covered by oxides.

2DP-073Quartz, Calcite

Porretta quartz sites, Porretta Terme, Alto Reno Terme, Reno Valley, Bologna Province, Emilia-Romagna, Italy

Field of View: 7 mm
Largest Crystal Size: 2 mm

Small but perfectly transparent quartz "diamond" measuring approximately 2 mm. The crystal is set in a vug of bituminous calcite. The matrix is a dark sandstone really rich in organic matter. The piece was collected close to the "Muraglione" on the road between Ponte della Venturina and Molino del Pallone.

5F0-CTGQuartz

Casa Calistri, Granaglione, Alto Reno Terme, Reno Valley, Bologna Province, Emilia-Romagna, Italy

Dimensions: 56 mm x 18 mm x 17 mm

Beautiful complex elongated fenster quartz from the classic locality of Casa Calistri. The upper termination is really transparent because of the small width of the crystal, while the lower termination is whitish and thicker. Unfortunately the lower termination is damaged on the other side of the crystal but it still is a really nice specimen.

H1K-FDKCalcite

Sasso di Castro, Futa Pass area, Firenzuola, Florence Province, Tuscany, Italy

Dimensions: 20 mm x 30 mm x 20 mm

Perfect glassy calcite rhombohedron measuring 30 mm on the edge collected at Sasso di Castro. In this locality calcite is commonly found in veins and the crystals are broken but in this case the calcite crystals were perfectly cleaved inside a clay pocket, producing beautiful transparent Iceland spar-like crystals.

NUY-LQYCalcite

Premia gneiss quarries, Premia, Antigorio Valley, Ossola Valley, Verbano-Cusio-Ossola Province, Piedmont, Italy

Largest Crystal Size: 10 mm

Pietro Grandi collection
Two generations of calcite crystals, the smaller one have the common rombohedric habit while the bigger one a flat hexagonal habit. Hexagonal flat calcite crystals, the biggest one measures 10 mm, associated with epidote, coming from the Premia gneiss quarries; their transparency is excellent, while taking photos it was hard to see the crystals on camera!

VH5-TCWCalcite, Datolite

Sasso di Castro, Futa Pass area, Firenzuola, Florence Province, Tuscany, Italy

Field of View: 10 mm
Largest Crystal Size: 6 mm

Really beautiful light yellow calcite crystals, the biggest one measures 6 mm on the edge, with nice growth structures set in a vug filled with white datolite crystals.

YJ3-U6MQuartz

Porretta quartz sites, Porretta Terme, Alto Reno Terme, Reno Valley, Bologna Province, Emilia-Romagna, Italy

Dimensions: 63 mm x 45 mm

Marco Bertolani collection
Amazing flat skeletal quartz measuring 63x45 mm collected by Marco Bertolani in the locality of Fosso degli Olivacci. The transparency is perfect and the yellow clay inclusions are very aesthetic. The flat shape of the crystal is caused by the small width of the crack where it grew.

10T-GDPZircon

Codera Valley, Novate Mezzola, Valchiavenna, Sondrio Province, Lombardy, Italy

Field of View: 3 mm
Largest Crystal Size: 1 mm

Nice small perfect crystal of zircon measuring 1 mm inlcuded inside a broken crystal of acquamarine which shows a yellowish radioactive halo around the zircon. It isn't aesthetic at all but it's very rare material gifted to my father by the the very famous local strahler Dante Colzada who found overall the best alpine acquamarines in Codera Valley in the 1970s.

HER-RA8Diopside, Actinolite

Monte Cervandone diopside deposit, Mt. Cervandone area, Devero Alp, Baceno, Devero Valley, Antigorio Valley, Ossola Valley, Verbano-Cusio-Ossola Province, Piedmont, Italy

Field of View: 10 mm
Largest Crystal Size: 12 mm

Detail of the termination of a complex diopside crystal measuring overall 12 mm set on a matrix of calcite associated with actinolite. The transparency of the crystal is great just as the colour. The FOV is 10 mm and the width of the crystal is approximately 4 mm.
