My notes say this is fluorite, but I'm not sure. I welcome an expert opinion. Similar to the quartzite image, here again showing depth effects, semi-transparency, and specular retinal rivalry. This image shot with the Panasonic Lumix 3D-1.
Compare this image to "Calcite" shot with the Fuji W3, which actually shows the exact same crystal (hence my uncertainty about what this really is) shot from the same distance. The Fuji has a wider stereobase so the depth effect is stronger and specular rivalries more numerous.
