This is the first piece from the Saindak Cu deposit Ive ever seen,

Here are a couple of Congolese pieces.

Pyromorphite from "Cumberland", J R Gregory specimen, with original label and box, the address on the label dates it to 1866 - 1874.

Here are some pictures I did of a Fluorite from the Greenbank days of Rogerley Mine.

Very nice old pyromorphite ( https://www.mineral-forum.com/message-board/viewtopic.php?p=32708#32708 )

Thank you Tobi, I find these old samples very evocative, all the hands they have passed through on their journey to my shelves and all the changes in the world these samples have survived.

Here is a Gregory Calcite likewise merely labelled "Cumberland" At a guess Id say somewhere in the Alston Moor area possibly Rampgill because of the Fluorite casts on the back of the piece, but I could be totally wrong. Rampgill was worked from as early as 1690.

Any advice on cleaning samples with 140 year old paper labels glued to them would be appreciated, the best advice Ive had so far is "Dont"

Strontianite from North Yorkshire and a really strange Fluorite from Skears Mine, its a bit dinged but a fascinating formation. Id be interested to know how the purple cube formed ? its a real brain teaser.

A few more, these are from Asia. Afghanite that is double terminated, Quartz with Chlorite patches (Not in the photo) and one of those neat orangey coloured Topaz crystals from Skardu.

I just got this Gypsum it looks kind of unreal.

This first piece looks like a gargoyle. Calcite on galena included Quartz on Galena, From Bulgaria. The second an ear. The ear seems to have some cast's on it, my guess would be they're after rhombohedral Calcite crystals.

You rarely see material from Hartsop Hall, just the odd older piece, this piece has yellow Fluorite to 5 mm and Galena to 2 mm. I also came across these purple Fluorite's labelled as from El Hammam, I liked the way one has octahedral modifications on the edges and the other is octahedral. I was wondering if the piece showing the octahedra is etched.

Hi Nurbo. Now Jordi is on a trip but both of us are pretty sure that the last two fluorites come actually from Tounfit, Boumia, Morocco: deep violet color, modified cubes as well as octahedra, zoning...

If you do not mind, I can change the labels.

Regarding the first fluorite, the modifications seem to be rhombododecahedral modifications, not octahedral ones, or at least the main modifications.

I arranged with Jordi and Carles Curto to publish several questions on these amazing fluorites from Tounfit, but my time is very scarce this year. I will try to do it as soon as I can.

Greetings

Hi Antonio,
I dont know re the locality, I bought them. Your right about the modified edges though, thanks for pointing out my mistake, modified corners give octahedra edges give dodecahedra.

[Jordi Fabre]

Is true that these Fluorites don't match el Hamman but now at home and with a better vision of your images I should recognize that them don't match Tounfit neither, so let El Hamman, as you have this information...

So last Saturday I took the 100 mile up hill and down dale journey to visit a very rainy Bakewell and spend some money I couldnt afford, one Vendor (Who's name escapes me) had the first piece Im going to show today, Ive seen oodles of Sand Rose's before but never from Kent!!
I also bagged this pretty little red/orange Campylite from Dry Gill, one day I may try and trim it some more, there are a lot of partials on it which detract from the main event, as it were. There did seem to be a lot of Campylite up for grabs this year.
