Vintage sterling silver celtic knot necklace pendant vtg

This was from a box of jewelry I got and it was a single earring, the post part was marked stamped 925 but I took that part off to make it into a necklace pendant because I only had one earring. The bail is not sterling but plated silver and very nice, The Celtic knot is sterling and has the aged patina look. you could polish it back to bright but I would not. measures- 1.75" long with bail you could take the bail off and put it on a chain without it, I think it looks good like it is with it. box 23 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, 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, Jay feinberg, kenneth Jay lane, Germany, 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
