thanks for this nice video; one thing: the twins you show are mineralogically no twins but intergrown or parallel grown crystals. Except for the staurolite, that is a real twin , where two crystals intersect at a specific angle.
Thanks so much. Never figured it out at school. It's really helpful!!
Great vid
Very helpful! Thank you.

Very nice video
That almost looks like pilot mountain you are at when the video first started
