These tumble stones of fossil coral jasper are unique in every aspect. There display a range of different colors and patterns. Circular patters are created due to cross-sectional cutting of the coral tubes, while tubular patterns represent longitudinal sections of the coral tubes. Other patterns are also visible on account of cutting at different angles. The striking colors are due to the presence of mineral impurities. Overlapping patterns are formed due to entrapment of corals in different layers within the host stone. Tumble stones can be carried in the wallet, pocket or purse. They can also be placed in the home or office at suitable places. They are also used in key chains and pendants. Fossil Coral Jasper is believed to possess healing properties, including the ability to alleviate stress and remove negative energy.
