Art Nouveau Platinum Opal and Diamond Filigree Ring

A lovely opal and diamond filigree ring from the Art Nouveau (ca1910) era! Crafted in platinum, the ring holds a beautiful boulder opal cabochon at the center of a filigree mounting. The striking opal is an Australian ironstone boulder opal, showing beautiful blue and green flashes contrasted against a dark brown host rock. Four old mine cut diamonds decorate the fine filigree wirework border in bead settings, adding a gorgeous sparkle to the design! Collectively, the accent diamonds weigh approximately 0.35ctw, and have varying color and clarity ranges. The lacy cutouts, fine milgrain details, and hand-engraved accents provide the perfect finishing touches to the exquisite setting. Underneath is a smooth band which tapers towards the back. This wonderful Art Nouveau ring would look wonderful worn on special occasions, or could make a beautiful gemstone engagement piece!

Measurements: The ring has a finger size 6.75 scant, but could be resized. 

Condition: The overall condition of the ring is excellent. Besides normal surface wear, there is no apparent damage to the handmade platinum setting. The opal and all of the accent diamonds are intact and securely set.
