This is a big, solid, 18kt, yellow gold, men's ring. (It's marked 22k) I had an antiques appraiser look at it and she gave me the appx. value, but could not locate the hallmark in any of her references. I thought that maybe one of you might know who the maker is. It looks like it might be from the UK, or Ireland in style, but there are no British marks on it as far as I can see. Thanks!
