An interchangeable jewelry system forms a bracelet, necklace, earring, and/or ring jewelry piece. The interchangeable jewelry system comprises at least two jewelry strand sections, each having a central body located centrally between two end walls comprising oppositely attracting mating magnetic portions placed opposed to one another on the central body.
