I had a friend volunteer to wear a pair of Argentium® Sterling earrings for me. She has only been able to wear high karat gold. Any gold under 18 karat would cause redness and swelling in her ears. She was also not able to wear Sterling Silver. Wearing Sterling Silver would result in redness and swelling in only an hour or two. Often this would result in infections.
My friend wore the earrings for over a week with no ill affects. She liked them so much she asked me to make her some more.
After the earrings were created, I put them in the oven at 250 deg. Fahrenheit for 20 minutes. I did this to attempt to raise the germanium oxide on the surface of the earrings. After the earrings were taken from the oven, I sterilized them with alcohol.
This test was by no means conclusive, however it was a very positive result for this one person. I am looking forward to doing more testing.
