Surgical steel post, nickel free. Gold-tone plated brass in antique gold finish and swarovski pearls. Handmade, so variations in stones & materials are expected. Pouch & box included. See photos for size approximations. All my listings are from my personal collection, therefore are in pre-owned, gently used condition (worn once or twice). Ret $298, selling mine at listed price. Final sale. *To maintain a peaceful & easy closet experience as much as possible, kindly note offers outside my acceptable range will be left unanswered/declined, no counteroffers are sent, and repetitive low offers may be blocked. Thank you for your understanding and interest.*
