I run a pawn shop and buy used jewelry. I had a customer try to sell me a diamond engagement ring and band set today. The style of the main ring is the "Brilliant Ribbon" as labeled by Tiffany & Co. At a distance it looks ok, but when I put it under a 10x magnification loupe the "Tiffany & Co." hallmark on the main engagement ring doesn't look right...it's all in block lettering, rather than the usual serif type style I see on other pieces (including the accompanying band that was presented with this ring). Furthermore, other authentic "Brilliant Ribbon" pieces I've seen sold online seem to always have the exact ctw engraved on the opposite side of the inner diameter of the ring, whereas this one has nothing on the opposing side. In addition, the overall craftsmanship on the main ring doesn't look right to me compared to other authentic pieces I've seen online.
The "Tiffany & Co" hallmark on the accompanying band ring looks more right to me (compare the photos), but the concerns on the main engagement ring caused me to conclude the main ring setting is at the least counterfeit and not authentic Tiffany & Co. When I shared my concerns with the customer who presented the ring to me she was stunned and thought I was dead wrong. Any Tiffany & Co. experts out there that can chime in on this piece? I tried to take some close-up pictures in bright lighting to show the detail. Notice the contrast in markings between the main diamond ring and the accompanying band.
