Tarnish on vintage Schlumberger bangles

[Mayacamus]

Hello PS'ers
I am considering starting to collect Schlumberger bangles, but several vintage ones Ive seen have varying degrees of gold tarnish.
Is this some thing I should be concerned about? If not, how do I remove the tarnish?

Thank you
Maya

Is there a gold polish that won’t harm the enamel?

What karat gold? High karat gold shouldn't tarnish...?

It’s 18kt gold

Have you tried just a good soak in mild dish detergent and water?

If it’s definitely Tiffany (with paperwork) why not return it to your nearest store for refurbishment. Those bangles are pretty pricey and it would be a shame to damage them.
