Went diving with SD Monday and wasn't getting very much until towards the end off the day when I uncovered a gold chain and cross. We thought it might be 10k gold because it was dark looking.I took it into have it tested and it turns out the chain is 18k (15.52g) and the cross was 14k (2.01g), they said it appears to be very old because of the crude construction and it also bounced between 18k and 22k but the acid test narrowed it to 18k. Also found a small silver chain, a broken silver ring and a trashed watch that turned out to be interesting, on the back it has the name Robert Brinkworth Port Huron Wings 1971-72; he turned out to be an important figure in the hockey world. Also the watch was found in a Lake far from Port Huron. Found several other junk items. The gold coin turned out to be a Condom package, what a disappointment (ha, ha), maybe i will give it to SD for getting me into water hunting. HAPPY HUNTING!!!!
