WTB 2mm Platinum Knife Edge Band size 6-ish Tiffany

[e2the3rd]

I’m curious about the Tiffany 2mm knife edge band in platinum, hoping to find a great deal. I think I’d prefer a size 6 - 6.25 - possibly 5.75 or 6.5 could work. There are a couple on eBay I know but wanted to see if anyone here has one they never wear and would like to part with. Doesn’t have to be Tiffany but same/similar measurements etc, and as far as I’ve searched this doesn’t exist
