Zales White Gold and Diamond Cocktail Ring. I bought several yrs ago. The stamp says 10K RL. I had to Google this. It means rolled gold or the gold is 41.7% and the rest is brass or copper. The diamonds are definitely real but I don't remember the carat count or how much I paid. I tried to find receipt but its been over 6 yrs. I keep all my gold rings in a cleaning solution and this ring hasn't tarnished at all. So I was surprised to learn its not solid gold. Offers welcome
