Counter weight machine to open a geode of amethyst
PUMI1256-8
We created a strange machinery: a mechanism to open a geode. This natural stone from Brazil is an amethyst geode. It looks like a simple stone, but when you lift the upper part, it reveals an inside full of natural purple crystals, in a geode of rock crystal. It works with counterweight which hold the lid in balance. But mainly, it works with the surprise effect!
