Tiny geode, Mexico

A tiny geode from Mexico, blue-grey with a crystal lined interior.  It is discreetly attached to a silver coloured base so that it stands and displays well.

I think that this will work in either 1:12 or 1:24 scale settings but please check the measurements. 

7/16 inch (1.1 cm) wide, 5/16 inch (0.8 cm) deep and 1/4 inch (0.6 cm) tall.
