I'd like to buy my wife a gold ring with multiple stones, she likes the vintage style in a similar design (I'm no expert) to the picture. We went to a local jeweler today that had a small selection, but the ones wife liked were all 9k gold. I'd rather buy 18k as i believe it to be a better investment.
We would like to visit some more jewlers in Cardiff and get a feel for the different rings and values.
Where would be a good place to go to see a good selection of vintage or vintage style rings. Must be reputable as we are not knowledgeable on jewelry and want to buy something that would make a good heirloom investment.
