A big, gorgeous and flashy specimen from Poland, a slice through essentially a boulder of alternating bands of three different minerals that were laid down in successive layers, similar to the way agate gets its bands, but with an exotic mix of minerals here rather than just quartz (as with agate). This specimen came out of the collection of Dave Stoudt, who was stationed in Poland for a decade and was able to buy from miners and dealers during his time there.
