Can any one help with this Birmingham Hallmark. Hallmark 925 silver convention in scales - maker or sponsor HPJ - 925 - anchor.
These appear on a well made Tiffany Choker. All links soldered; appears a quality piece. However, I took the Choker into Tiffany & Co Sloane Square and they said it wasn't one of theirs. They weren't sure it was silver. A mystery. Who is HPJ and are they still in operation. Is it a total fake, but how has it got these marks on - the link is soldered, not just pinched together. Is it from another country and someone has paid to have it tested and stamped. It's not a Tiffany hallmark - i'm at a loss. I will send it Tiffany but I wondered if anybody here had any suggestions.
All ways appreciated in advance.
