Dude! That ring is cool! It looked awfully familiar though. I knew I'd seen it or something like it myself so I went back and did some digging (no pun intended), and I was right! I've dug one up that is strikingly similar in design. It's like the little brother (or sister) to the ring you found. Only difference is your ring has two rows of gemstones, and the ring I found a couple of years ago only has the one row of gemstones. Still though, you can see for yourself, they had to have come from the same manufacture or jeweler I would say.
Wow.. small world huh? I found mine at a local High School Football field near some bleachers, in Central Kentucky. It's a long LONG way from the beach. <grin>
