My wife gets all the lady jewelry I find - It's funny, when I started metal detecting in Santa Cruz at the beaches, I found a silver ring and my wife was a distance away, I waved at her to come and she came reluctantly and slowly.. but was excited to see the lady's ring and quickly claimed it. from then on, whenever I waived for her to come to me, she runs excitedly lol.. these rings you found are these type she would be having in her collection.
If any of you have trouble convincing your wife to not gripe when you get a new detector.. bribe her with the lady jewelry finds and things will go much better for you
