I have a beautiful vintage necklace with faceted cut clear crystal or quartz beads. They have a nice weight to them. It is 19 1/2 inches long with 1/2 inch crystals. They are strung on a thick string with a silver tone twist clasp. I don’t see any metal markings so I don’t know what the metal actually is but it doesn’t stick to a magnet. The last picture shows the prices of similar necklaces for sale online ($180-$450). See my other ads for jewelry, artwork, home decor and more.
