Hi Vic. I appreciate your comments! I am sure that, if we lived close to each other, we would have been out on many outings together. Best regards.

Hi Pierre and Riana, thanks for showing us your latest acquisitions! I'm impressed by the large carrollite crystal on matrix, and the green fluorite from Riemvasmaak, but the 'crazy quartz' from Brandberg is my favourite :-)
Regards, Mike
