Biwa Pearl Sterling Silver Pendant and Chain 925 Necklace Baroque Pearl

Romantic and trendy biwa pearl necklace in sterling silver setting with sterling twist chain. I think is may be artisan made, as the bottom of the pendant is etched with the letters ZOR - possibly a signature? It's beautiful no matter the provenance! Excellent condition, just needs a polish if you want that fresh silver look but I kind of love the wabi sabi of the tarnished silver with this pearl. Chain is app 44cm total length
