Also called old Amita from Japan. The black background part I believe is pure iron and inlaid with 24K gold and pure silver motifs. I see it here and there and think it was mostly from the WWII era. I'm with beachkid on the value. https://www.google.com/search?q=amita+jewelry&biw=1366&bih=643&source=lnms&tbm=isch&sa=X&ei=dRRHVPmQHMj-yQTKqYK4Cg&ved=0CAYQ_AUoAQ#tbm=isch&q=old+amita+japanese+jewelry&imgdii=_
