New vintage silver dolphin pendant necklace (Montréal)

New vintage silver dolphin pendant necklace (Montréal) Industrial rustic minimalist Fine Silver Box chain Chain hallmark: GDR STG Has that pretty warm silver colour that old silver spoons have. Nice “slinky” feel, smooth movement. New vintage c. 1970s. I thought GDR: meant German Democratic Republic or East Germany (c. Post-WWII - 1990 unification). But it is from a Montreal jeweller who came once a year with beautiful gold and silver. Dolphin hallmark: 14K BUT I THINK THIS ISA MISTAKE. They don’t often make mistakes but I believe this is silver not gold. It is priced accordingly. 👍
