Onyx and Dyed Green Coral create this unique necklace! The Large Black Onyx faceted Square is quite a focal Point! The Onyx focal is a 2 Inch Square! The Coral is dyed Green to give an unusual coral look! Together they combine and are held securely by an antique Sterling Silver Toggle! Earrings to match are available! Also, Onyx earrings would make a great compliment for this necklace
