Hello, and thanks 
for visiting our Web site!

Our names are Richard & Cheryl Sittinger and if you love minerals and learning about them, we’d like to invite you to join our Mineral of the Month Club! We have two levels of membership (Junior and Deluxe) to suit your level of interest.

Each month we send our Club members a wonderful mineral specimen, properly labeled with name and locality information, and a fascinating three to eight page write-up that explains everything you want to know about its unique properties!

We have two levels of membership available– with the only difference being the size of the specimens.
