 Posted: Jan 09, 2009 17:05 Post subject: Quartz perimorph after Calcite |
|
|
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

Jon,
nice to "see" you here, small world :-) but not unexpected.
Another one: Tourmaline var. Elbaite from the Malkhan pegmatite field (Malchany), Transbaikalia (Zabaykalye), Eastern-Siberian Region, Russia, size 2.8 x 2.2 x 1.8 cm.
Got this one in the 1990s from J. Badanina, St. Petersburg, who worked on those deposits as PhD thesis - still one of my favourite gem beauties.
Cheers
Roger
(BTW your parcel grows ;-) )

last for today ...

P.S. .. still struggling with Carles database .. it requires administrator rights ... so i got it working now (and well working) but it would be nice if it worked in restricted accounts ... Carles, do you read ;-) ?

Hi Roger!
I have the calcite!
This is an old pict of your quartz perimorph after calcite.
Looks like your quartz, but this one is smaller.
