5F0-CTGQuartz : SiO2

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 : CaCO3

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 : CaCO3

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

Largest Crystal Size: 10 mm

Pietro Grandi collection
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!

YJ3-U6MQuartz : SiO2

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 : Zr(SiO4)

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 : CaMgSi2O6, Actinolite : ☐{Ca2}{Mg4.5-2.5Fe0.5-2.5}(Si8O22)(OH)2

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.

NUW-F6YQuartz : SiO2

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

Dimensions: 55 mm x 43 mm x 17 mm

Amazing flat skeletal quartz with a very particular shape collected and gifted by my friend Marco Bertolani. The transparency of the crystal is just incredible and it has some very beautiful clay inclusions. The crystal is flat meaning that it grew in a limited space inside a crack where it couldn't develop that much its thickness.

Pizzi dei Piani, Madesimo, Spluga Valley, Valchiavenna, Sondrio Province, Lombardy, Italy

Field of View: 4.5 mm

Small group of three blue trasparent anatase crystals measuring 2 mm across. The colour of the crystals varies from deep dark blue to light blue and yellow. The specimen was collected and gifted by my friend Edoardo Mottarella.
