Is this gwindel quartz?

[rienhartman]

I have  specimen of quartz from Izizauen, Morocco that looks like gwindel quartz.
I'm not an expert, just an amateur.

Can someone tell me what kind of quartz it is?

Thanks in advance.

I have anothter specimen from the same location.

What kind of quartz is this?

Thanks in advance.

Hello Rien,

although I'm addicted to quartz, owning many gwindel specimens and having had a close look at your photos I'm not able to tell you defintitely whether your specimens deal with gwindel quartz or not. At first look I'd say: No!
It would be easier if you could offer pictures that show whether there is a torsion or not.

Best regards

Robert

Robert, I have no idea wahat a 'torsion' is, but I will make more pictures tomorrow.

Maybe you can tell me what kind of quartz it is.

Kind regards,
Rien

Hello Rien.

You must make photos from the lenght side, not from the frontside.
It is a gwindel, there must have a rotation in the lenghtside.

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

Michael.

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

Hi Rien,

in my opinion your last but one photo shows a kind of rotation and I think that this specimen is a gwindel quartz.
To prove it you should take a picture holding your camera over the top of this piece without changing the position of the specimen like you would photograph a spiral staircase downstairs or the DNA-helix mentioned by Michael.

Best regards

Robert

The Last zwo Fotos Show that this piece  is a Gwindel.

Hallo Rien,

Maybe this pictures can give you a better idea about gwindl-quartz.
I sketched a gwindl-quartz from Galenstock, Kanton Wallis, Schweiz.
One sigth from the front, perpendicular to the c-axis.

Is this gwindel quartz?

This is the view from the top, on the c-axis.

Is this gwindel quartz?

By the way, gwindles are rare variety of quartz. But esthethically relevant gwindles are extraordinary rare.

Best wishes, Klaus

Hello.

The picture 2579 shows good the rotation and this is a gwindel quarz !

Thank you so much all for your explinations and pictures.
I now finally see what makes the quartz a gwindel
I now can see myself that the other specimen I posted pictures from is not a gwindel.

Kind regards to all.
