This unusual solid australian opal has a soft gray body tone with subtle blues and lilacs and a charcoal line running diagonally across. I've set it in all brushed silver with a fringe of soft labradorite and sky blue topaz. The 4mm band measures a 6 1/2.
Argentium silver for enhanced tarnish resistance (.940)
Focal measures 1 1/8 inches wide an 7/8 of an inch tall.
