Chlorastrolite Pendant with Michigan Greenstone Gem cut by Chris Cooper Set in Hand Stamped Sterling Silver

Chlorastrolite Pendant with Michigan Greenstone Gem cut by Chris Cooper Set in Hand Stamped Sterling Silver has wonderful patterning and chatoyancy.  

These rare stones are found only in one region of Michigan.  This one comes from a vintage collection, polished by a different "now" veteran rockhound and lapidary artist who passed the stone on to me.  It took (let's see... since 2016) so a whole decade for me to set and publish the piece with this stone!!  Wow.  
May it be an heirloom piece for some many to come!
