Our Sacre Coeur necklace is cast in sterling silver with one bronze accent medal. A Sacre Coeur medal (Sacred Heart of Jesus/Sacred Heart Basilica in Paris) is teamed with a Miraculous Medal & accented with a Mary with baby Jesus medal (Jesus on back). Our necklace can be worn 3 different ways by clasping at different points. There is a mix of two different chains. Where the chains meet, we’ve added a small jump ring so that one can clasp there, making all of the medals align. If clasped at the large O ring, there is a more obvious use of the extension. Measures 24" to center O ring.
