Couple of years ago I get this scratchy, broken signal. I passed it up the first time thinking it was rusty iron.
On the way back and virtually no other signals, I decide to see what it was. Pulled the scoop of wet sand out and it was sparkling all over.
I finally found my first heavy, gold rope chain. It glistened and sparkled.
When I got home and washed it off,,,,,CRAP....said BRASS right on the clasp. Heart breaker.
I'll never forget that sound and never pass it up again.
So glad yours turned out to be the real thing.
Congrats on great find... makes up for all the other rings you didnt find.
