trusted websites for piercing jewelry that ships to canada/metal question

just starting my piercing journey with some stacked lobe-age and am totally lost on where to find reliable and durable earrings/piercings in yellow that ship to canada that don’t have ridiculous shipping costs. etsy seems to have a few stores that seem trustworthy but again shipping is expensive if you don’t bulk order, or it’s not jewelry that i’m interested in having in my ears!! i’ve put some style reference pictures if anyone has any suggestions for places that offer similar styles :)

i have yet to get a straight answer when it comes to the best metal to have for “fashion” leave-in earrings. my piercer says titanium and full 18k yellow gold are great which is a-ok but i don’t quite have the budget for 18k and i haven’t found very many titanium styles that i really like. is sterling silver with gold plating ok for an earring that i’d leave in most of the time? would 10k or 14k gold be fine to leave in? or is it best to have titanium for the “leave in” styles and make my fashion styles ones that i don’t wear in the shower/to bed etc.

any help would be greatly appreciated!!
