These small silver Hearts w/Bale charms come from a company in California called TierraCast. They are 100% made in the USA and are nickel free! This beautiful Engraved Heart is made using Cadmium & Lead free Pewter and is plated in .999 Britannia Fine Silver. This heart is perfect for hanging from a Dee Ring but not a Ball Stud Ring or O-ring or it will hang the wrong way. The dimensions on the entire heart charm are 11.6 mm wide x 16.6 mm high and the internal diameter of the loop is 2.6mm. I include a small silver jump ring when ordering this charm. This little Engraved Heart charm is perfect for a Princess DDlg collar.
