NEW sterling silver initial K pendant and chain 16 inch necklace

This is a new in original packaging pendant and chain necklace that’s unbranded with no tags. I removed it from its original bag to photograph and placed into a new bag in better condition. Note that the pendant looks like it has some signs of use on it from simply just polishing. It’s unclear if this is yellow gold plated over sterling silver or just sterling that’s tarnished from an element. After polishing the pendant , it looks more silver , leaving the chain with a gold color. Pendant is not purity stamped but I did acid test for verification.  Chain measures 16-18 inches. Initial K. Unknown maker. Total weight is 1.71 grams. Reasonable offers considered
