I am a Comedienne, whch has nothing to do with "rocks" but I do make jewelry in my spare time and have always loved rocks and minerals...Maybe the person your are referring to just has a "interest" in rocks, or maybe it's a hobby for them presently or one they may be getting into...I think groups should be OPEN to various people from other occupations to allow them to gain knowledge of the things they might want to research or bring into their lives...No offense intended to you personally, but everyone has a right to experience other aspects in life, as long as they do not push their own personal beliefs or are offensive directly to others...HAPPY selling/buying to you...I have watched this group for a long time...
