Tiffany Metro Heart Ring hallmarks pics?

[CoolKat]

Hi everyone! I need your help please

I have Tiffany Metro Heart Ring that I received as a gift. I've been really happy with it but we parted ways & I want to probably sell the ring. Ring is in very good condition & it's hallmarked. But then I noticed that the hallmarks are a bit off (?) especially the "750"

I thought Tiffany put the metal in front of these numbers, e.g. AU750, PT950, AG925?

I looked up another same ring for sale & the other one actually has AU750 instead of just 750.
Waaaaaaaaaaaaah!

Do any of you have this ring? If you do, do you mind looking at your ring's hallmarks to compare to mine?

I am anxious now! Have I been duped all this time?
Waaaaaaaaaaaaah!

Here is one on Ebay... looks to be signed the same way.
That's good!

Thanks, Rubies-R-Me! I still have my doubt because this one on eBay has that AU in front of the 750

I wonder if it's because my ring is older?

Hello again!
I wouldn't be too worried.. seems like in every signed piece there are variations on how they are signed I guess depending on the factory they were made in as well as the year they were produced.
I also think that most of the Tiffany jewelry that is counterfeit is silver.. not gold.
Just my 2 cents.

Hi!
Just found another one on Ebay that is marked 750 without the AU.
