I designed this 3cm stylized sea turtle to be work either as a pendant or, with the appropriate fitting, as a brooch (see the digital renders of the back of the piece). Available from my store on Shapeways in various materials, from plated stainless steel to glossy .925 sterling silver, from $12.80 to $52.00
