We normally have a good selection of minerals from the copper mines and mineral prospects of Michigan.  Sometimes we have fantastic examples of coppers, silvers, and half breeds.  Michigan is also well known for its fine celestine crystals and other minerals such as datolite.

Front view but laying sideways

OKN-325      Celestine       Maybee, Michigan.  Ex. Harold L. Dibble collection.  A large grouping of several double terminated crystals.  The piece measures 16.7 x 7 x 7 cm overall.  The crystals are in fine condition and all are lightly embedded in a small section of matrix.  The base of the matrix has one broke crystal facing downward (this is seen in the first image which is the back of the piece) as would be expected.  It displays damage free if positioned with the matrix downward (which is frankly impossible without a custom base or stand).  These big, fine crystals make the specimen top heavy so Harold had it lying on its side for display.  $425
