Had a good two hours at low tide today, the ring in the picture gave me a rush until I got it home, the stones won't go green, not diamonds, maybe next time.
I see it once and awhile, there is one beach in my area that at the correct tide and swell will produce an unusual amount, you just have to be there on the right day. I took my granddaughter down to that beach a while back hoping to score on sea glass and found none??
