Very nice specimens and pictures.
I really enjoy the “cubic” one (Calcite-WagholiQuarry-India-2cm-99.jpg)

Hi Stretch,
All killers!! I particularly like the Dal'negorsk nail and the benitoite, though I could find a home for any of them!

It has been a while since this thread was active. The photos below show a recently acquired calcite specimen from the marble quarries at Estremoz, Portugal. This location is known to produce complex calcite twins and I would like to learn more about this particular twin type. The larger crystal (shown upright in the first photo and horizontal in the second photo) has a couple of interesting faces which form a "w" shape on the edge of the rhomb. The crystal on the right side of the photo has a prominent shallow notch running along the edge which appears to be where two flattened rhombs come together perpendicular to the c-axis. At the top there is another intersecting rhombic form. Any explanation about this specimen is welcome.
