Second 24K chain I found ever. First chain is the top one in the second pic. This one marked .999. Last one was 30.1 grams and 24". This one was 20" and 16.4 grams. I dug a hole and watched about 8" of chain slide out the scoop. I pulled it out the ground so quick youd picture a Robin eating a nightcrawler after starving for weeks. Left the beach before breaking out the magnifier. Switching to the 17" CTX coil to cover some beach paid off I think Chain design looks sort of like corncobs? I may use this one and some other 10K to make me a custom 18K pirate ring later with a sapphire eye patch? Also found someone's gold plating copper cent experiment
