Her shop, Lullaby Design (click on the name to go to her site), is located in Molfetta's old town on Via Morte (which translates as Death Way, but don't let that put you off!) just past the Chiesa della Morte. She can make you a piece of jewelry to order, to coordinate with a particular outfit or to suit your individual style, and she also repairs existing items.
Her prices are reasonable and she's a lot of fun. Definitely worth a visit if you happen to be in town!
