Vintage Oval-shaped, Silver-plated Blue Kyanite Cufflinks, and Matching Tie Clip

Pre-owned by a family member who kept it stored in a jewelry box in a smoke-free home for over 50 years. After research, it appears the stones are Kyanite. The patent # on the tie clip is for the spring clip of the tie clip dating from 1958. These items are in beautiful condition. I do not clean vintage items and leave that to the discretion of the buyer. All vintage items will show signs of wear consistent with age, as should be expected. I take close-up pictures of the items so the details are clearly visible. It can make items look bigger, so please review the measurements in the photos. If you like the item, make me a reasonable offer and let's make a deal.
