This gold ring also contains…
5,527 ppm Mercury,
1,214 ppm Arsenic,
2,867 ppm silver,
10,066 ppm titanium, and
22,812 ppm copper.
Non-detect for lead with an XRF Instrument.
Like this ring set, most of the gold I have tested has also tested positive for mercury.
This is among the reasons I do not recommend gold jewelry.
