cowri shells are always a special find. These are from the Roseland Peninsula in Cornwall. Yes the common 2 spot European cowri but actually not all that common. This one shows her true colours when dressed with a tiny bit of coconut oil. Enhances the colour and brings out the spots. This delicate wee shell looks amazing on the sterling silver 18" neck but i can charge the length of necklace if required. Possibly going down to 16" could look amazing. If you want a different length chain , just ask. This comes on a standard 18" sterling silver chain.
