Vintage 14K Gold Filled Stud Earrings With Lots Of Natural Red Ruby Stones

Gorgeous stud earrings with real natural Earth mined ruby stones of deep red Pigeon Blood color. Possibly, from Burma. They vary slightly in color, which is what true natural stones do. These rubies are bright and sparkly, and really fire up in direct sunlight, and these pictures don't do them justice. They were examined by my jeweller and confirmed as natural. 14 karat gold filled. Not sure what the base metal is. Could be 925 sterling silver because of the white color showing slightly on the edges of the round parts. The backs are matching in shape and stamped 1/20 14K GF and 1/20 12K GF (as I can't find the second 14K GF one).
