Tiffany Etoile vs Whiteflash Benchmark ScatteredDiamond band

[Sundial]

Sundial thank u for the pic. It's gorgeous!

I have a question. I came across a preloved plat tiffany etoile band. But the hallmark is different from the usual online ones I see T&CO this one spells out the full name Tiffany & CO.
The seller said she bought it from a local boutique in Singapore where I'm at. So I called the store to find out and was told by the SA that every country has different hallmark??!!
But they can't authenticate pieces or tell me over the phone what is the hallmark on the etoile band. I'l try and pop by sometime this week to see it for myself.
Though I'm completely surprised to hear that different countries have different hallmark on their tiffany rings. Any one heard of this?

Hi Kalmen, thank you. I have three rings from Tiffany and I just checked the hallmarks. Two of them have the T&CO but the third has Tiffany & Co spelled out. All three were purchased in the US.
