Dangle earrings are crafted from bent/curled horseshoe nails, suspended from sterling silver earwires. Measures approx. 1 3/8 inch from top of earwire to bottom of dangle. Horseshoe nails are made of steel....they can and will patina dark over time and with wear...though this happens less often with earringsdon't worry, it looks really pretty this way! Keeping your horseshoe nail jewelry from getting wet will help delay the patina process...if your horseshoe nail jewelry does get wet, just dry thoroughly and use a small piece of fine steel wool to keep it bright if need be. Artisan Crafted.... All of my items, whether jewelry or decorative pieces, have been handcrafted by me in my Finleyville, PA studio.
