Thank you for your order and feedback! It is unfortunate that your necklaces didn't arrive looking as expected.
The CHN0109 is made from 316L surgical-grade stainless steel with an 18K gold PVD finish. Unlike traditional plating, PVD bonds the gold to the steel in a vacuum chamber, which makes it highly resistant to tarnishing and fading.
18K gold PVD often has a warmer, richer tone than bright yellow plating, and it can look deeper or slightly uneven in some lighting. This, or residue from packaging, can sometimes look like tarnish. A gentle wipe with a soft, dry cloth often helps.
If the pieces still look discolored, please email us with photos, and we'll gladly make it right with replacements.
