Ran the Nox hot. Some of this gold with breaks or open will hit in the iron range mostly down in the ground a bit. At least on my machine. The Love God pendant never hit on the positive side. But the 50 tones told me something was there. If you notice, even the silver is cracked or open. Be safe out there. When these places are hammered to death you got to dare to be different. The ring is 10k. The two pendants are 14K. And the earring with diamonds is 750. Gold luck out there!
