Fluorescent Room Turlock Rock and Gem Show
March 14th & 15th, 2020
Turlock Fairgrounds 900 N Broadway

Come see the amazing colors in our Fluorescent Room.

We have approximately 15 exihibit cases inside our dark room, exclusively for our fluorescent exhibits.

These rocks, minerals and glass are naturally giving off the amazing colors you see. All of these exhibits have special UV lights that the samples are reacting to.

Stan State and MJC Earth Science Professor Mike Whittier, will be at the identification table all weekend to talk about his passion - fluorescent minerals - and answer your questions.


We are lucky to have several guest exhibitors from the Fluorescent Mineral Society that display their world class displays. There are few places that you would be able to see such collections!
