I noticed the waves were getting big so I went for a beach hunt to see if some sand had shifted. Sure enough there was a lot of green crusty clad. One ring is 925, the other is 10k. Haven’t tested the stones because I don’t have a tester. Also my brother took back his scale. The medallion is stamped 750 (18k). Unfortunately my carbon shaft on my stealth scoop snapped part way through the hunt. I continued on only hunting gold signals. It was a great day but it broke my scoop and almost broke me!
