This is a sea shell loosely modeled from the typical Camino sea shell worn by pilgrims on "El Camino de Santiago de Compostela" also called "El Camino Frances" (or in fact on all the other pilgrim routes that leads to Santiago de Compostela). In Spanish a sea shell is called "Concha".
This one is ment as a necklace - it's pretty big, but still small compared to the size of the typical ones worn by the pilgrim. There are two wholes for the thread/necklace, the diameter of the holes are 1.67 mm. The "Buen Camino" is not on the original model, but you can write me if you want another one with writing on or inscription.
I also have matching earrings in the shop.
