Affordable jewellery shops Santorini

Hello!

I’m currently in Santorini and I’m looking for recommendations for affordable jewellery (necklace €30/60) that won’t tarnish.
I’ve had a look in Fira but I was overwhelmed by the amount of shops and wasn’t sure which ones were selling cheap jewellery for high prices.

We have a car so happy to travel around.

Would love any recommendations.

Thanks!
