Hello.

With these last photos I momentarily suspend the theme of minerals from the Italian Alps.
I think six months on the same topic are too many even for the kindest visitors.

I'm pleased to share in this forum one of the largest plates of hessonite garnet from Piedmont Alps.

Best regards. Stay safe.
Sante

Hello Sante,

I like both the Pyrite and Cinnabar. Good size, interest and quality.

Stay safe.

Thank you, Don.

You are very kind, but since I play at home, I don't have much merit with Tuscan minerals that I will continue to share (covid 19 permitting...).
It was far more laborious to assemble the Alpine collection.

Here other two Tuscan specimens.

Stay safe.
Sante

Hello, Tobi.

Thanks for your kind comment.
I dedicate to you next Tuscan specimen: first for your fondness for galena and second because it shows a certain "Neudorf" style.
I hope you like it.

Greetings from Gavorrano.
Sante

Wonderful galena specimen Sante. I love the association with siderite, sphalerite, and quartz.

that is indeed a fine galena! It looks like the crystals are spinel twins, too.

Many thanks to all of you.

Michael, I'm happy that you like it. I was fortunate to find it in an old Tuscan collection. :-)

Pete, your very experienced eye (despite your recent surgery) sees better than before: yes, they are spinel twins. Take care. :-)

Tobi, coming from a galena lover, this is a big compliment. :-)

Rob, I'm aware that I'm a bad photographer. Simply, in this case the piece was photogenic. :-)


Campiano mine, despite being a pyrite mine, didn't produce collectible specimens of this mineral. In return it gave very beautiful samples of anhydrite and fluorite.

Warm greetings. Stay safe.
Sante

Hello.

When, in the 1960s, I met my wife we were students in Rome, both from two different Italian regions.
Intrigued by her accent, I asked her where she was from. She replied: "Gavorrano". "Gavorrano..?". "Yes, where the pyrite mines are". "Pyrite..?". "O.k. I'll bring you a piece...".

My collection was born and developed in the name of pyrite.
While being attracted, like all of us, to aesthetic pieces, over time I began to appreciate the variety of crystallizations, modifications, associations, etc.

This premise was necessary because I will share many pyrite samples, since this has been the most exploited mineral in Tuscany since the Etruscan times, if not before.
I hope you find them interesting.

Warm greetings from Gavorrano and take care.
Sante

All the dodecahedral faces modifying the cube are jagged:
- sometimes the growth facets are sub-parallel to the dodecahedral modification;
- other times they are parallel to the diploid. In this case we are in the presence of a modification of the modification..!
On the cube corners there are:
- octahedral modifications, with indented surface;
- diploidal modifications, with smooth surface.

A fifty faceted floater crystal.
A modified cube by dodecahedron, octahedron and diploid. (6 cube + 12 dodecahedron + 8 octahedron + 24 diploid/triacisoctahedron = 50).
The triangle in the upper front face belongs to dodecahedron. The triangle in the upper left side belongs to octahedron. The surrounding three faces belong to diploid.

 Dimensions: 26 x 20,3 mm
 Description:
Different view with the octahedral and diploidal modifications in evidence. This octahedral face is quite odd: the lustrous central part (although not triangular) might be the real octahedral modification, while the opaque, surrounding, triangular (not complanar) frame might be a diploidal modification of first order; so that the external three bigger faces would become diploidal modifications of second order.
Sorry for the nuisance...

Hello.

Four pyrites more from four different Tuscan localities, but all of them with a common denominator.
The crystallographic literature defines the pentagonal-dodecahedron as an "impossible crystal". Let's say, to exemplify a lot, that in a dodecahedron there cannot be regular pentagons. Even the most perfect of pyritohedrons is an "impossible crystal".
So what to say about such deformed pyritohedra?
I hope you find them interesting.

Best greetings from Tuscany.
Sante

Hello Sante,

Very impressive Pyrite crystals. Boggles the mind.

Stay safe.

Don

Sante,
I was so excited that someone else is interested in the variety of crystal faces of pyrite. My first image is of a small crystal with an octahedra face on a cube. It's from Elba. The dealer showed me that pyrite could have other forms than the cube. That got me going down a road of adventure.
In 2003 I presented a program on how to identify pyrite faces using Peruvian crystals at Tucson. It can be found at the Rochester of Science web site - rasny(.)org
Photos of two of my favorite Italian crystals are also attached.
'Sorry about the photo quality. It is a rush job.
