Identifying Your Pinky Ring: Hallmarks & Origin

Question
I have been given a little ring for my 'pinky' finger- 24 x .02 pt diamonds with the hallmarks 375, anchor, date stamp Z, QVC. Can you tell me roughly how old or recent it is, where it was made? Thanks.

Answer
HI JUDI,

WITHOUT ACTUALLY SEEING THE RING IT IS DIFFICULT TO TELL. 375 AND THE ANCHOR ARE BRITISH HALLMARKS FOR SILVER AND GOLD AND THE DATE STAMP Z IS PROBABLY A MODEL DESIGNATION. I AM NOT WELL VERSED ENOUGH IN HALLMARKS TO BE ANY MORE SPECEIFIC.
THANKS
PETER
