These earrings are made from a tooth that I found at Caspersen Beach in Venice, FL. (My happy place!) This tiny tooth has been cast and lovingly handmade into a pair of earrings. Since this is a handmade item, made one at time, please allow for slight variations in your earrings from those that you see here. These magical studs measure approximately 10mm wide x 8mm long. The cast shark teeth are sterling silver or brass, and the studs are sterling silver.
