The Field Museum in Chicago has such an exhibit.  It is a single case, maybe
6' wide and 4' deep, with a small window in front (maybe 18" square).  It
periodically switches between flourescent light and incandescent, and has a
couple non-mineral objects (a t-shirt, a piece of cardboard) for contrast.

Contact Peter Laraba (312-922-9410 x587) in Education for info on exhibit
development, contents, labels, choice of minerals, etc.  Contact Trigg
Waller (312-922-9410 x343) for info on lighting, design, related material,
maintenance, etc.
