Gerard Yosca gunmetal flower chain necklace (signed, collectible)

Perfect condition necklace worn only a few times. Designer is Gerard Yosca, piece was designed and made by hand in NYC’s Garment District. Yosca name is signed on piece. Stones (large center circle and small rhinestones) are secure and clasp is very strong. Purchased in ~2009 in New York so almost vintage. Have seen similar pieces listed on 1stdibs and other auction sites for $250+. I still love the necklace but never wear jewelry anymore!
