Tarnish-resistant and Stronger
Argentium silver 935 is a modern sterling silver alloy, containing 93.5% silver. The traditional sterling alloy (92.5% silver + 7.5% copper) is modified by removing some of the copper and adding the metalloid germanium.
This is the result of research by Peter Johns at the Art and Design Research Institute (ADRI), School of Art & Design, Middlesex University in 1990.
The revolution necklace made with a touch of germanium, Argentium® Silver presents a bright-white color that is closer to fine silver than traditional sterling, yet is highly resistant to firescale and extremely slow to tarnish under most conditions.
