Thank you for viewing. I am unsure of the authenticity of the amber. Engraved 8476 It's a large stone with a sense of weight. Please refer to the photos. Note 1) Please leave the choice of Yamato Transport or Japan Post to me. Note 2) As this is a used item, there may be some dirt or scratches. Please purchase with understanding. #Amber #ShowaRetro #8476 #Earrings
