Vintage Agate Stone Tie Tack in a Gold-Tone Setting With T Bar abd Chain

Pre-owned by a family member, no chips or damages this tie tack has attached the chain and T-bar. The stone is a form of agate stone, may be moss agate. I am not sure. This tie tack comes in its original Anson jewlers box. This tie tack has been in a jewelry box in a smoke-free home for over 50+ years 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
