Fossil Coral cabochon pendant & leather necklace. The cabochon is approximately 1.5 inches in length on natural black polished round leather. The necklace is adjustable from 16 inches to 32 inches by sliding the knots. Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans & secrete calcium carbonate to form a hard skeleton. Fossil Coral lore values the gemstone with the ability to ward off evil spirits. Sailors preferred fossil coral as a good luck charm of the sea. They believed it had the power to avoid bad weather. This belief has been taken further to mean that it has the ability to ward off bad storms in life. Fossil Coral Pendant Adjustable Leather Necklace Handmade By Chris Hay
