SARDA Sterling Silver & Polished Green Stone Pierced Drop Earrings

SARDA Handcrafted Creations sterling silver & polished green stone, unsure what the stone is. The 3rd photo depicts the stone color the best. (Sarda display card not included) beveled edge all around the stone. Both marked 925 & Sarda one earring shows the Sarda stamp better than the other. Earrings 1.25” long & just over .5” at the widest end. Bought these back in Oregon in the mid nineties.
