I don't have a really clear view of the mark, but it certainly looks like Tiffany to me.

Do you think I'm correct to date them pre 40's they're clip on but they have that modern look though the hallmark tooks to be quite old the T&co stacks on top of eachother and ster 14k below

In their 1929 registration of the mark on your earrings with the USPTO, Tiffany claimed that it was first used in commerce in 1900. I wish I could help you further, but I just don't have the expertise. If a guess will suffice at least for now, I'd expect them to be from the forties or fifties. Good luck with your research.
