Jack's collection currently numbers about 3,200 meticulously documented specimens covering most sizes, from thumbnails to very large cabinet pieces. He has many species, not just the most popular twenty or thirty that you see at mineral shows, although he does not go in for extreme rarities. His specimens run the gamut from modest to elite, all exhibited together in 14 packed display cases; included is the big tanzanite crystal that won Jack the Lidstrom Award at the Tucson Show in 2007. Always happy for the chance to socialize with other collectors, Jack is a member of the informal group of San Francisco mineral collectors called the Crystal Gazers.
