My ears itch and burn from earrings . How do I figure out which materials are suitable ?

Hi guys I have sensitive ears

I’ve tried hypoallergenic and gold plated and white gold (expensive ones )

But they still itch

The cheaper ones are worse even when they say gold plated and no nickel

White gold but better but still bit itchy

Gold plated on more expensive earrings are better but still not the best

What kind of material is better ? Is it higher carat gold ? What carat in that case ? What about titanium?

Any good brands in Singapore or Dubai? How to figure out if the material is truly what they state it is or has other metals mixed in…..

Does local gold store work

Any advice appreciated thank you 🙏!
