** THIS IS A LARGE BEAUTY - RECENT FIND -

A chalcedony geode is a hollow rock with a rough,

unassuming exterior that hides a sparkling, smooth, or bumpy

(botryoidal) interior lining of microcrystalline quartz.

It forms when silica-rich fluids seep into rock cavities and

slowly crystallize over millennia
