@stingray I've been chatting with ChatGpt about this all day lol. There's one brand I know that is safe and tarnish free. Pura vida. Their prices are very low but I wore their stuff in Mexico in mud, saltwater, freshwater, shower and no tarnishing. I have a microplated gold chain that's holding up pretty well but it doesn't shine like the day I got it :(

I think Pura vida might use titanium? Also I guess I should say I have only tested their earrings, bracelets, and rings, not necklaces. My sister gives me a butt load of jewelery and clothes lol 😅 and other various items.
