I would say it's possible that the buyer did a switcheroo. Either way you can absolutely tell the difference between your pic and Tradsey's.
Is it possible that the item was switched out? The bracelet looks much worse for wear, there's dullness from use, either that or the angle of after pics are different. I feel for you... does Tiffany come with serial etc?
I was going to suggest that the buyer did a switch too.I inspected the bracelet under magnifier, it IS my bracelet but scratched and tarnished now. customer returned it immediately, then it took 11-12 day for Tradesy to process return. so go figure.
and here's another comparison pic of before and after. it's not a bad angle, macro shows the scratches that were not there.
May I ask how you can tell it's your bracelet?
