Ostby Barton Ring Art Nouveau 10K Rose Gold Band Carved Onyx Intaglio. This is a stunning antique Art Nouveau signed and hallmarked OSTBY BARTON ladies ring from my personal collection. It is time to start passing along some of the beloved jewelry that sees only the light of day when I open the lid to the jewelry box! The ring has a wonderful black onyx intaglio carving of a Greek or Roman soldier or warrior. The band is rose gold with yellow gold applied floral “prongs” whereby a petal of the flower wraps the stone and holds its precious cargo in place. The band also has the most precise beaded edge or border halfway round the band on each side as well so does the top of the bezel that holds the stone. The inside of the band is marked or stamped O. 10K and has the Maltese cross hallmark or maker’s mark. THE OSTBY BARTON JEWELRY FIRM WAS ESTABLISHED BY ENGLEHART C. OSTBY AND NATHAN B. OSTBY PARISHED ON THE TITANIC IN 1912. Measures size 6 on the ring mandrel and may accommodate just a slightly larger finger due to the openback setting. Weighs 2.8 GRAMS.
