KEZEF18k Gold Over Sterling Silver 1mm Box Chain Necklace Made in Italy | Sterling Silver Plated in 18K Gold Necklace for Women

Tell me please, How it looks at every day wear for several months?

Does this chain really turn green after a few times wearing it?

My mother can no longer open/close clasps. does one of the ends have a jump ring that opens? A jeweler could add the pendant and close it. thank you.

Does this pick at shirt fabric effectively ruining your shirt?
