The curiosity shop features unique or hard to find items, many of which come from a collector/geologist who was actively trying to amass a comprehensive collection more than twenty years ago.  Included are old stock rocks, collector’s pieces, one-offs, rocks from currently depleted mines, or unusual items that do not fit the categories within the store.
