Reasonably priced necklace chain that doesn’t tarnish?

[GoldenGlobes]

Hi everyone, I’ve recently started a new hobby making necklaces and earrings. I am on the lookout for some necklace chain (on a roll ideally so I can cut it to length - I like long necklaces!) which won’t tarnish and make my neck turn a funny shade of green! Any tips please?

I’ve found a few craft and jewellery shops online but was hoping to find some real-life experience. TIA
