How perfect would these be for a tropical wedding? Each piece in this series by Nervous System is a unique, one of a kind composition. Tiny circles of varying sizes make up the complex patterns that mimic the natural forms of corals. The pendants hang on 16"-18" sterling silver chains, and the pins are affixed with a nickel silver pin and clutch. They are also offered with a silver finish, and in several other unique coral-like patterns. The delicateness of these gives them just the right amount of formality, in my opinion.
