Lovely earrings, as everyone else mentioned, these look like typical natural seed pearls used in the old days. Many of them were set deep inside the metal so taking them out would be difficult. I would rather keep them where they are, very unique and much better than replacing them with cultured...

Thanks for the information everyone. I believe it is a maker's mark, tried to search but couldn't find anything similar to this.

Did the store tell you these pearls naturally colored or treated? the price you paid was certainly not cheap but I would expect the real naturally colored golden south sea pearls to be more expensive. A quick search online I found this dyed golden south sea necklace at around $4000 from Nieman...

these do look small in size for South Sea golden pearls. do you mind to tell us how much you paid for these?
