Yes it is a very nice specimen!

Indeed very very nice, Carles. Even if the pictures are quite small it's obvious that your specimens are really fine and a pleasure to view. So don't be too humble, you can be proud of your rocks. If there are any more, please keep posting ...

About 230, plus some 70 more from Catalonia with lower quality but somewhat high local value, most of them field collected by myself.

This is my Spanish pyrites shelf (13 pieces), although the biggest two specimens are not here for being too heavy. Anyone interested in seeing them individually should go to
http://www.mineral-forum.com/message-board/viewtopic.php?p=2768#2768 and http://www.mineral-forum.com/message-board/viewtopic.php?p=2789#2789

The photo is not good because of the wrong lighting from the bottom up.

Here is a picture of a temporary assortment of specimens from different countries that for some reason don't fit with the other showcases (43 pieces).

Very nice, thank you, Carles.

Two questions:
The large white crystal to the left of the center, what is is? Calcite?
The green mineral beneath the realgar on the right side, is that Riemvasmaak fluorite?

Hi Carles. Nice rocks, nice displays, all of them. Where did you get your display cabinets??

Oh, and the Naica gypsum, single crystal on martix, dead center, bottom row. Did it come to you with a Romero label? It very much looks like one that I acquired for Miguel, and he decided that he had enough gypsum specimens from there, and that I could just keep it. I sold it at the Pleasanton, California show in 1979 or thereabouts. Just curious.

Thanks.

Ed

Hi Tobias!

The large white crystal you are talking about is a dolomite that was posted at http://www.mineral-forum.com/message-board/viewtopic.php?p=2636#2636

The other, you are right, is a Riemvasmaak fluorite, posted at http://www.mineral-forum.com/message-board/viewtopic.php?p=5786#5786

Thanks once again for your comments,

I got them for free. When I bought my current apartment the previous owner unexpectedly asked me if I would mind to keep several showcases that were difficult for him to take out. He was not a mineral collector but he and his wife used to spend their leisure time building paper models, that then were exposed in the display cabinets. Of course I answered 'no' right away (I did NOT mind). However, they are not the best kind of showcases to show minerals, so I'm not very happy with them.

Such gypsum came to me with no collector label, so I assume it is not from the Miguel Romero collection. But there is no certainty. As you well know some specimens change hands many times and then the original labels are often missing. This piece is posted at http://www.mineral-forum.com/message-board/viewtopic.php?p=4684#4684

Thank you for your interest,

No, there is no rutile in that showcase. I understand you are referring to a group of three Australian tourmalines. If not, please let me know.

For more details, photos of these specimens are posted at http://www.mineral-forum.com/message-board/viewtopic.php?p=5674#5674 , http://www.mineral-forum.com/message-board/viewtopic.php?p=6262#6262 and http://www.mineral-forum.com/message-board/viewtopic.php?p=6543#6543

I'm glad you like the pictures.

Thank you!

Thanks Carles! I went to the url you provided and was able to take a good close look at piece 6349M. What a beauty it is indeed!!! You can see right through the crystal to the matrix below. Looks like the crystal has been deposited on a matrix of carbonate (limestone or dolomite) breccia. It is actually possible to study the underlying matrix (spacing and size of the fragments, things like that) through the crystal itself. Wow!

The piece I had in mind is similar, on a single piece of similar/same matrix, but without the breccia (or whatever) fragments. I believe it was a slightly darker colour as well, darker grey, not quite black.

Probably similar vintage though.

Thanks for the reply, and the opportunity to look at your stuff.

Oh, and congratulations on your freebie display cabinets. Woo Hoo!!!

Later,

Ed

Hi Ed!

I think the gypsum matrix is neither limestone nor dolostone. It might be a complex material that in my Catalan mother tongue is known as 'marga', in English 'marl' or 'marlstone', and is "a calcium carbonate or lime-rich mud or mudstone which contains variable amounts of clays and aragonite" (according to the English Wikipedia). Most sources, however, refer to 'calcite' or 'limestone' instead of aragonite.

Such specimen as a whole seems rather good, but by making a search on the net you can find many others, also from Naica, that are much better ( for the casual reader: we are talking about this: http://www.mineral-forum.com/message-board/viewtopic.php?p=4684#4684 )

Hi Carles

Very nice specimens you add from day to day. Especially the last one ( http://www.mineral-forum.com/message-board/viewtopic.php?p=18366#18366 ) is a phantastic piece. Can you shoot me a private message how much a piece like this is. I want to look for something like that in Munich and want to know what prices (at least a range) are on pieces like this.
Thanks.

Pyrite, quartz, calcite?

Group of pyrite crystals on quartz. Overall size: 71 mm x 52 mm. Main pyrite crystal: 31 mm wide, 29 mm on edge. Weight: 149 g. The crack that is visible in the photos seems to be natural, not man made, likely caused by very old tectonic movements. Among the quartz there are other crystals, colorless and transparent, with rhombohedral habit, that might be calcite or dolomite.

The crystallography of this specimen is very interesting. The main crystal is basically an octahedron {111} but also shows pyritohedron {210} and rhombododecahedron {110} faces. Although octahedrons and pyritohedrons are quite usual in pyrite crystals, rhombododecahedrons are really rare. Please see more details about the habit in one of the photos below.

Huanzala Mine, Huallanca District, Dos de Mayo Province, Huánuco Department, Peru.
