Without any silver marking (perhaps there is one under the stone,on the finding itself) it's not easy to quote a price ... but not much more than $15 (if silver)in this area on a very good day , valhom .
Kinda looks like a mass-produced finding (the metal ring) for mounting stones in , as found in 'rock shops/lapidary supplies' , to my eyes .
It's actually fossilzed asbestos (tigers-eye) !
