@monikozi It is a beautiful object both outside and inside the case, see my 365 Album of today. I bought it as a gift for my wife on our 50th. Wedding Anniversary back in 2019, she loves it. A piece of triviality, it is inside its original cardboard box from the jewellers (I got it from an online auction site) which has the retailer's name and address which amazingly coincidentally is the same branch of jewellers in Richmond Surrey that where all those years ago we purchased Beryl's wedding ring! I had no idea when I bought it but the box is definitely the same era as the ring, the late 1960's. Serendipity or what!
@monikozi You are right about the goose bumps, it did me when I opened the parcel and saw the box it was in! I think it is Portuguese gold work but am not absolutely sure, the hallmarks, which you can just about see above the left flower at 1 o'clock in the scroll, are unreadable I am afraid. Wish I could find out more about it.
