• Iron (Fe): 226 +/- 42 ppm
• Cobalt (Co): 221 +/- 28 ppm
• Nickel (Ni): 52,200 +/- 900 ppm
• Copper (Cu): 121,400 +/- 200 ppm
• Zinc (Zn): 17,800 +/- 300 ppm
• Titanium (Ti): 476 +/- 195 ppm
• Nb: 1,490 +/- 39 ppm
• Molybdenum (Mo): 907 +/- 38 ppm
• Indium (In): 39 +/- 8 ppm
• Gold (Au): 207,700 +/- 4,700
• Bismuth (Bi): 83 +/- 35 ppm

Note: With non-destructive testing, given the size of the ring it does not fill up the testing area (a circle about 1 cm in diameter) of the XRF instrument. With this consideration, the amounts of metals detected should be considered as comparative levels (totals compared to other metals detected) not direct percentages of total content – with all metals detected listed. So, for example, the reading of gold at 207,700 ppm does not mean that the ring is only 20% gold – but that – compared to the other metals the gold was the most prevalent metal.
