Aqua chalcedony briolettes dangle from sterling silver ovals. These earrings hang from Kiiker's exclusive Argentium Silver ear wires.
Argentium® Silver is a sterling silver made with germanium rather than copper so that it is highly tarnish-resistant, so these will not darken like sterling silver. Germanium or copper and other metals are added to fine silver for strength since silver is a very soft metal. It is also hypo-allergenic, which is why I use it for many of my ear wires.
