Thank you, Michael, I'm glad you like my new specimens, I really appreciate them as some of the best in my collection!
And yes, indeed a great thing to have some "mineral friends" nearby :-)

Your 15 cm alpine quartz posted above, if undamaged, may be in my opinion a world class specimen.

Thanks for your appreciation, Carles! The specimen is undamaged, yes. The tip is not one sharp tip (maybe once distorted during growth and then healed) but undamaged and nearly complete. There are some inclusions, bubbles etc inside, but all faces of the 15 x 9 x 9 cm main crystal are complete all around. And there is some coating (the usual chlorite stuff or something like that) on some faces of the backside so the crystal is only that completely transparent from that point of view. Nevertheless an undamaged specimen with (imho) great aesthetics all around. For me, as a quartz collector and a fan of alpine smoky quartzes, this specimen is a perfect one, one of my personal highlights in the collection :-)

Thank you, Carles. I like that specimen a lot, its visual makes it a perfect center piece. Not all crystals on the edges of the specimen are complete, this is common in this locality, but all those parts are recrystallized so there is no visual damage. Some of the crystals even have phantoms inside - I really like that new Madagascar locality :-)
Regards
Tobi

A very aesthetic specimen thanks to the additional faces in the upper part of the beryl and the surrounding mica crystals.

I agree that it looks as Cavnic but however it could also be from Herja (the "campanoid" form of the Quartz is indicative that it also could be Herja) so I changed the locality to "Maramures, Romania" just to be sure... 😏

Thank you, Carles, I like the specimen for the same reasons. The aqua crystal is neither large nor of intense colour, but it has this additional faces and the upper part is completely transparent, you can look through 2,5 cm of water-clear beryl and see the bottom of the muscovite crystals ...
Those of you who own world-class aqua specimens from Pakistan with free-standing 10 cm crystals of sky-blue colour may laugh at me that I mention this little and unspectacular detail, but I just love the clarity of the crystal ;-) Here are some closer photos of the part where you can see through the crystal:
| Mineral: | Aquamarine, Muscovite |
| Locality: | | Chumar Bakhoor, Hunza Valley, Nagar District, Gilgit-Baltistan (Northern Areas), Pakistan | |
|
| Dimensions: | FOV 5 cm |

Thank you, Jordi, a good idea and definitely not a wrong locality information :-)
I think the photo above was ok but I tried a dark background, maybe better for this specimen:

Well, I would not call the quartz magnificent, it's just a 4 cm group of "ordinary" milky quartz from Cavnic, but nevertheless thanks, I'm glad you like the specimens :-)
