That's what I thought also, the small round circle stamp appears to have a letter possibly an R or A or maybe it's just a symbol. The 6 sided mark has some kind of a symbol I don't think this was purchased in the U.S. If it was purchased in another country and did have gold it wouldn't be marked by 10K or 14K, correct? with the marks on the bottom could it be gold plated silver? Thank you for your information
