Really an outstanding faden quartz! Never seen before in this size!
Thanks Volkmar! This one was purchased quite some time ago and back then it wasn't too hard to find large pieces.
Indeed hard to find in such a size nowadays. Last year I had the chance to get one (~ 18 cm) with larger crystals for a really good price but I thought too long about it and - surprise, surprise - it was sold very quick :-(

I'm glad you had luck purchasing such a great one, Mike!

Best regards

Thanks Tobi! So sorry to hear you missed out on a nice large specimen. I too have missed out on pieces that I have pondered too long on ....

I guess we all experienced that, but the money you "save" by missing one specimen allows you to get another one ;-) And looking at your awesome collection, you should not worry too much about pieces you missed :-)

What a special piece! I have recently become aware of and in love with Quartz growing at angles like this, this piece appears to be growing epitaxially. Is this just a fluke or do you think there was a catalyst for this?

I really don’t know. I have seen others that exhibit this type of growth/appearance.

Several years ago I bought one of these for the fluorite inclusions (interesting fluorite habit) and later recognized it also was a Japan Law twin. Perhaps the smaller crystal has that orientation too.

It might be a Japan Law Twin. Hard to measure the angle.

Hi Mike.

Fantastic.

I think it may be the comandant from Coronel Murta.

Really amazing.

Nice fluorite specimen, Mike!
My first thought was rather Surprise Mine / New Mexico, I've never seen something like that from Naica. But I know there are many different kinds of fluorite from Naica so I won't doubt that locality information.
I love the zoning inside of the crystals!
