Vintage Tiger Eye Gemstone Beaded Gold Necklace

Vintage Tiger Eye Natural Gemstone Beaded 1/20 12k Gold Filled Clasp Necklace This necklace features natural Tiger Eye gemstone beads on a 25.5" strand. The clasp is marked "1/20 12k" (gold filled). The clasp does have to be pushed closed after opening but is completely functional. I am unsure whether the gold metal ball beads are also gold filled or only gold tone. There is hardly any wear to be noted on this piece - a beautiful vintage gemstone necklace!
