J. Crew ? Sapphire necklace glass gold O links statement beautiful euc 26" vtg

Vintage? J crew? This had the quality and look of lots of J. crew pieces, not all jcrew have the lifeboat spring ring ,alot have this lobster clasp and many pieces of jewelry can lose their brand hang tag, I've had several confirmed jcrew with lost hang tags. This looks to be from them I'm not 100%. It's very nice and high quality, deep dark sapphire blue foiled back glass rhinestones. They are open back too for more sparkle. 26" long total wearable length, this can be worn shorter for sure. box 30 I sell in my closet and have tons of other brands similar to list such as weiss, Stanley Hagler, Alice caviness, Demario, Navajo, James Avery, miriam haskell, Jomaz, hattie Carnegie, juliana, Lee sands, Barse, native American, Navajo, Fairchild Baldwin, coro, vior,Donald stannard, lisner, renoir, Eisenberg, Christian dior,Givenchy, ciner, carolee's, hobe, Ben amun, Tiffany and co, Vendome, Alexis bittar, Judith jack, kjl, vargas, Sherman, Nolan Miller, Elsa peretti sharra Pagano, Jill Fagin, raebird, Jay feinberg, kenneth Jay lane, Germany, talbots, Lilly pulitzer, J. crew, Japan, Hong Kong, Simon ju, Thelma deutsch, Erwin pearl, monet, Napier, Cynthia Daniel, Judith McCann, hollycraft, Joan rivers, Elizabeth Taylor, Anne klein, Oscar de la Renta, Moschino, roule and co, julia Vaughn, jose and maria, les Bernard, Heidi daus, silpada, Sorrell, and more, so keep a look out I list daily
