Also one of my favourites (although it is too large at all for display ;-) ) - a perimorph of quartz after calcite crystals, hollow at the back and quite nice if illuminated with backlight (but also a bit of esoteric then :-) ) so i decided not to post that picture.
Size 59 x 29 x 16 cm, Cavnic, Romania.
The largest specimen in my collection (i prefer small cabinet) and also an "older" one, from the early 1990s.

This was one of my first "expensive" specimens i got (i was a student then and only little money) ... acquired at the Munich show in the mid-1980s - and still one of my favourites. An almost total "floater" of wolframite with siderite, apatite, quartz and pyrite/marcasite. Overall size 16 x 13 x 6 cm.

Thanks Jordi,
so i will go on ..
Specimen with a highly lustrous undamaged stretched/modified cube of second generation galena on dolomite with first generation dull (cubo)octahedral galena on limestone matrix. Also some iron sulfides and chalcopyrite present.

I first wanted to sell this one but then i compared with other samples i have from there and must admit that it is quite worth keeping.

Size 9 x 7 x 4.5 cm
