I have only been detecting for about 8 months and I have found zero rings. This weekend I decided to take a trip out to the Rhine River by Eltville, Hessen Germany and go along a small rocky beach outside of town. I found about 8 dollars in Euro clad, 5,50 in Deutsche Mark coins and these three rings. The first on the left is .925 sterling and I believe the turquoise is real on top but cannot prove it either
. The one in the middle appears to be 10 or 14k gold. Finally on the right is stainless steel ring from Fossil. Was a nice trip and really enjoy hitting the beach with the F75. If anyone has an opinion about the gold ring I would like to hear it.
