Long enamel rings necklace

I got several of these pieces this year. The jungle violet and amaranth pink were beautiful. I was really looking forward to the jade as I needed more green jewelry but when it arrived I was shocked. Unlike the others, the links on the jade were all scratched up and dull. The others have nice gleaming links, like they were treated to maintain the shine. It almost appears like the jade missed a bath of some sort. Thinking it was just a bad one, I ordered a second one in jade, this time in the tiered type, but it also had the same dull, scratched finish unlike the others I've ordered in different colors. Hopefully others have better luck. Pretty necklaces otherwise.

Love this, good quality and looks really nice. I plan to buy more colors!
