These two pieces of dalmatian Jasper are not really a true Jasper at all. Instead this is known as dalmatian stone and is a crestline version of chalcedony. That's not just these pieces this applies to all dalmatian Jasper. 
We routinely buy new rock tumblers and when you buy new rock tumblers they send you rocks to tumble. Obviously we focus on tumbling Scottish rocks we have a bunch of international rough minerals kicking about the house. And it is time for some of them to go! 
We have two pieces of rough dalmatian Jasper ready for their new homes and ideal for further lapidary work.
