Scallop shell engraving, 7/8" x 1/2". Testing 9k. Secure closure, once probably closed a bracelet, much like the Scottish Pebble one above. Glass panel with no hair or anything else underneath. Scallop shells have been a symbol of travel and pilgrimage (snd spiritual journeys) for centuries. It's most famously linked with the Camino de Santiago (way of st. James.) A medieval pilgirmage route ending in spain. Pilgrims traveling there would wear or carry a scallop shell as proof of their journey.The shell's radiating grooves all meet at a single point, symbolizing many paths leading to one destination, a good metaphor for pilgrimage, where routes all over europe converged onto Santiago, Spain. In the Renaissance and after, even in the Georgian period, scallop shells became shortland for the idea of save travel / divine protection on the road. But! It could have just been a Neoclassical vibe - like Venus in the Clamshell?
