Is this gwindel quartz?

If it's a Gwindel than there must be a rotation/structure like a DNA-Helix.

Thats why we are asking for photos from other perspectives

Hi Rien,

as Lois says you should look at the level where you suspect the twist of the "stapled" Quartz crystals from above, i.e. the the long side of the crystals. If you caught this view on a photo we might tell you whether it is a gwindel specimen, but despite a good picture it's difficult sometimes if the "staple" is twisted only very slight. Maybe a look at Peter Serokas "Quartz portrait" in the "Mineralienatlas" or Amir Akhavans "The Quartz Page" could help you to understand what we are talking about.

Best regards

Robert

Thank you all for the replies.
It's a bit too technical for me.  Although I looked up pictures of gwindels, I can't find  'twists' in them.
I made some more pictures. Hopefully the right way this time
