This is a silver 925 ring with a natural stone purchased from Felissimo. The size is 11, as indicated by the engraving. The natural stone is a light blue color (see photo 2) and looks like blue lace agate, but I'm not sure of the exact name. Please note that the color may differ slightly between the photos and the actual item. The ring has some blackening due to oxidation and minor scratches. Please check the photos and understand that this is a used item before purchasing. There is no box. Thank you for looking.
