From the 1980's is this pretty little sterling locket with a blue sapphire color stone. It is marked 925 and Thailand. It's a lovely piece. Made more as a vinaigrette rather than a photo locket. A Vinaigrette is a small item that you stick in fabric or cotton that has been saturated in perfume or scented oil. It saves on perfume and a lovely way to "display" your scent!
Some people call this aromatic jewelry. A lovely piece. I have no idea if the stone is a real sapphire, but a lovely color and cut well! The sterling locket is 1 inch long and 1/2 inch across.
