My 2 year old loves to play with plastic beads. She only wears them in the daytime, never for sleeping or in the car. Sometimes I let her wear bead necklaces I have made with glass beads. I avoid anything with beads or charms that are big enough to be a choking hazard (pea size or smaller beads, nothing sharp). I'll probably wait until 5 or 6 to give her any real jewelery and even then it will just be for special occasions and I'll keep track of it. I have a few child size items left from my childhood (mom kept them safe until I was 12 or so and old enough to be responsible).
