Geode, white stripes
A tiny little real Mexican geode with incredible narrow white banding and glittery interior crystals. I think that the white layers show how the agate was deposited at one point in the geode's formation. For fun I have included a macro photograph of that part of the geode so that you can see the detail. The geode is mounted on a custom made brass base so that it stands securely.
I think that this will work in 1:24 scale as well as 1:12 but please check the measurements.
5/16 inch (0.8 cm) wide, 7/16 inch (1.1 cm) deep and 7/16 inch (1.1 cm) tall.
