A black coral branch necklace, designed as a single strand of elongated black coral branches, measuring approximately from 38 mm to 65 mm, completed with a silver clasp, gross weight approximately 86.50 grams, length 42.00 cm. The first new black coral bed found in centuries was discovered in deep waters off Lahaina, Maui in 1958. It is Hawaii's state gemstone. Slow to grow, when polished, the black coral has a high lustre. It is lightweight and so is perfect for large, bold pieces of jewellery., Cf. A.
