Well. As I indicated in the description, the pendant markings are Sterling and THEDA, the makers mark. THEDA is a company that was located in Rhode Island. They started their business in 1921, hence Vintage pieces tend to be at least 50 years old and yet normally under 100 years. Also, this was part of an estate find, which most items I received were estate or vintage. Also, having the "Sterling" mark as opposed to the 925, Which is .999 silver content I would consider the piece to be vintage. Now with all this being said, I could be totally off, however I do my best to research and provide the description of my items to the best of my knowledge. I hope this helps! Thank you! :-)
I indicated that the "Sterling" hallmarks is .999 silver, which These days tend to be .925. This also indicated the higher level of Sterling which appears to have mostly been used during these timeframes. My thought, and research. Once again great question. :-)
