Tiffany & Co. Product Lists?

Is there a website that lists products by T&Co. by year and/or collection? There is a “vintage” bracelet my aunt got from her grandfather (now deceased) when she was my age, and she gave it to me for my birthday. I know it’s the thought that counts, and I shouldn’t be scrutinizing a gift, but my aunt lies to everyone in the family about lots of stupid things. If this was something my late great-grandfather bought when he was alive, I’d like to know if that’s true, but I suspect she bought it at a pawn shop. No one else in the family remembers her getting this bracelet, but they admit they probably wouldn’t have remembered anyway.
I’ve already checked their website. I can’t even find this bracelet on the web… all the products shown are recent.
