This handsome necklace was purchased in Jamaica about 30 years ago. It is completely made of black coral. There are 21 branches of coral is graduating sizes. The smallest is 1-3/4" and the longest center piece is 3-1/2" long. The coral is black overall with a few areas in warm, dark brown. It is in mint condition and 18" long with a barrel clasp. It is highly wearable and makes a fashion statement of high drama!
