Vintage Garnet Bead with Gold Accents Necklace

This is a very beautiful quality garnet bead necklace with gold spacers. Measures 17.5 inches and is in VG condition. The clasp is stamped GF on one side and I believe 1/20 on the other. The small jump ring has been replaced. The clasp is original, I believe it is GF probably 1/20 14k Unverified as to the gems or purity of gold. Please see all photos. Thank you.
