Off the chart RARE Vintage 3 Layer Graduated Prong Set Rhinestone Necklace that is probably Austrian and done in sterling silver. The open backed crystals are done in rainbow colors and are exquisite! The photos don't do it any justice at all - the stones are not opaque, they are clear rhinestones but the flash and background make them appear so because they are unfoiled. If you've seen one of these necklaces before then you know how gorgeous they are. This one is delicate and dainty and ends in a lovely rhinestone drop. It measures about 18 inches. This would be great as a bridal piece with a strapless gown. This is from the same Estate as the Art Nouveau pieces and chunky Bakelite jewelry that I have in my store - the higher end stuff. Excellent condition and very chic!
