Abstract: A knitted fiber fashion accessory and method of forming includes at least one silver alloy wire knitted in a three-dimensional structure where the silver alloy is a precipitation hardened silver alloy. The fashion accessory can include means for attaching the fashion accessory to a human body and/or a decorative element connected to the knitted fiber structure. The method includes providing a silver alloy wire having at least one alloying metal; knitting the silver alloy wire into a knitted fiber structure; and precipitation hardening the silver alloy wire to produce a precipitation hardened silver alloy wire. The precipitation hardening improves yield strength and causes a volume reduction that improves flexibility or suppleness.
