Gorgeous wood fossil opal with lilac, pink and teal blue flecks sits wrapped in 22k gold on a base of 22k gold/silver bimetal. A fringe of sky blue topaz, pink sapphire, tanzanite on 14k gold headpins pick up the opal colors beautifully. Size 6 3/4 on a simple argentium silver band with satin finish.
Bimetal features a layer of high-karat 22-karat yellow gold pressure-bonded to a layer of bright Argentium® Silver. The gold constitutes a full 10% of the overall weight and the Argentium constitutes the remaining 90%. The front of the piece shows the gold layer and the back is silver. This is a cost-efficient way to achieve the warm look of gold jewelry.
Argentium sterling silver is a silver alloy where most of the copper has been replaced by germanium which lends greatly enhanced tarnish resistance over standard sterling. It is .935 silver--more pure silver than .925 sterling. In addition, argentium sterling is produced using only recycled silver.
