Apophyllite + Thomsonite Moonen Bay, Isle of Skye, Scotland, UK 12mm crystals Close-up of the above specimen. Difficult to photograph unless the crystals are in profile. The terminations show pyramidal modification, but none that were found had actual pyramidal terminations. However, the terminations are so clear and mirror-like, it looks like they are pyramidal, because of the optical effect within the crystal. (Author: Mike Wood)
