Hi all
I have this specimen with 10 (and more) crystals and minerals .
A small collection in one specimen.
Fluorite, Lazurite, Malachite, Azurite, Galena, Baryte, Quartz, Calcite, Limonite, Hematite…

I lag far behing with only 8... Maybe more, but hard to say.

I had in the past (maybe still have, but I don't know where, not at home...) a Panasqueira sample.
Carbonates: dolomite calcite siderite and apatite, mica, tourmaline, quartz, pyrite and chalcopyrite (millimetric for both), arsenopyrite included in the quartz.
But, ferberite, fluorite and cassiterite were missing....

Hi to everybody!
As the biggest majority of you should know (and I'm sure we all DO), almost all of the specimen (but for loose crystals and the majority of gemstones) contain at least 3 or 4 different mineral kinds! Quartz, calcite and mica (or serpentine) are contained in almost all of them and often we consider them "mother rock", thus accounting just of what we think "interesting" for our collection. Let me take an example of what I saw here above just now: the specimen Pierre showed here. What is interesting is the "rarest" mineral or minerals, in this case prehnite and analcime. Or, we coud start from the most "coloured" mineral, which gives a different appearance to the specimen, for example a well-coloured fluorite, or an azurite, or a malachite, etc.
But I think they are all subjective evaluations. Then take what I wrote here as a personal opinion, not an exact truth.

From my Mont Saint-Hilaire collection - peatite-(Y), ramikite-(Y), sabinaite, chabazite-Na, synchysite-Ce), gobbinsite. Not all would show in a single photo.

Just found this interesting old topic and I have to revise my information:

[bob kerr]

One aspect of mineral collecting I really enjoy is associations. Nothing seems to be more "sociable" in this area than sulfides. Here's two specimens that clearly show this trait. These are both from the Yaogangxian Mine, China and I plan to post a few photos of sulfide association from other localities.

The first specimen has at least 9 different species - so, here's a challenge - beat that!

Here's some other examples of sociable sulfides - these two specimens are from Trepca, Kosovo.

Hi Bob,

This topic was already discussed in this thread: Maximum number of minerals on a specimen so I've merged both threads.

Thanks for proposing it again!

[bob kerr]

Thanks Jordi - I didn't recall this thread - definitely makes sense to combine them.

I should have added something to the effect that the various species on a specimen should be visible - but no big deal. it is an interesting topic.

thanks again,
kerr, bob kerr

'Visible' is a good criteria, as the most I can think of are about 5000 (so far) - with a photo of the whole planet ;-)

Bob, I like the idea of 'sociable sulphides' I scrolled down your first three images and came to the fourth, without looking at the description first, and thought "That looks like Trepĉa!". Did you collect them yourself? Mine came from when I had a student placement at the mine in the summer of 1959. After retiring I wrote an article about them (not in an academic journal) and during its preparation was in touch with Prof Hyseni. Do you know about the book "Trepça Minerals Atlas" by Prof Bedri Durmishaj, Prof Sylejman Hyseni and Mr Ferat Shala, publ Mitrovicë, 2011

[bob kerr]

Peter - I have not seen this book but it looks like a must have - I assume there is an English version??

self collected?? I wish. would love to see what you have - please post.

For the past two Tucson shows a young guy from Kosovo, Enis Hajdini (hajdinienis at gmail dot com), has been in a room at the Riverpark Inn (Pueblo Gem and Mineral Show). he has had a wonderful selection of Trepca specimens at quite reasonable prices - and even more reasonable towards the end of the show.

it is definitely worth visiting his room. here's another specimen I got from him - resembling a bird's nest.
