The big kahuna of the cloud world, the Cumulonimbus is synonomous with thunderstorms.The international symbol for Cumulonimbus represents its vertical growth in the atmosphere… developing an anvil shape at the top, caused by wind shear, as it towers high into the atmostphere. Conditions can be dangerously stormy beneath a Cumulonimbus, but from a distance, they put on the most awe inspiring light shows on steamy summer nights. Handmade in Asheville of Argentium sterling silver, this one-of-a-kind pendent is on a 16-18″ chain. Chains are a delicate sterling link with deep purple Garnet stones. Also available plain, just make a note in your order.
