Vintage Carnival best Aurora Borealis Triple Strand Crystal Necklace Choker Rare Strung on Fine Chains Gold Clasps

I have a lovely triple strand of carnival aurora borealis crystal necklace strung on fine metal chains ( instead of strung on string)that then attach best to the gold tone clasp . This is from the 1950's. The clasp is unmarked to maker. The necklace with extension measures 17 inches, so for a smaller neck. I am able to wear it, but you could add another extension. The crystals sparkle
and reflect the light and appear in very good condition. I am new to Etsy, but I have sold for 20 years plus years on another site and also own a brick and mortar antique store of my own in Sedro Woolley, Wa .
