This rock crystal quartz necklace is quite magical. From the Art Deco 1920s or `30s, it is 32" long, made up of very beautifully cut, graduated (tested) stones that radiate light, strung on thin chain. The shape of the stones is gorgeous, flat on top and sharply angled on the sides. Amazingly, the smallest ones are cut exactly the same as the largest ones. A spacer bead is placed between each. With nice, substantial weight and a showy presentation, this is truly a classic! The safety clasp is unmarked silver metal and shows a little wear on the underside. No chips or flea bites to the crystals that I can detect. The largest stone is about 3/4" around.
