This is the object in question, an antique Chinese seal,. I’m trying to get a more professional opinion if it is in fact true jadeite****?? It was brought back from China in the late 1960’s by my grandfather and was purchased at the time as “antique”… I know the forum is about the gemstone which is the question that I’m intrigued with but if anyone has additional info like plausible era of the piece?? please share, I’m thinking late 19th century???..anyone who Can translate the characters? I’d be forever grateful!!!
