I've wrapped this blue-flashin' labradorite in warm 22k gold and combined it with a kyanite and swiss blue topaz. All three sit atop one of my swirled bands in oxidized argentium* sterling silver. Gold dots and a disc add sparkle. The ring fits like a 7 1/2. 

*Argentium sterling silver is a silver alloy where most of the copper has been replaced by germanium. It is .935 silver--more pure silver than .925 sterling. In addition, argentium sterling is produced using only recycled silver.
