Beautiful Victorian ring. Fancy mounting with beautiful detail. The ring is not hallmarked, but tested for 12K rose gold. There is one European cut natural Blue Zircon with 2 small Diamond accents. The Blue Zircon is held in place by rose gold leaves. The band has a pretty twisted design all the way around. The ring is a size 8 3/4, and I would not suggest re-sizing, as this may destroy the design on the band. The ring weighs 4.8 grams. Condition is very good for age. I would date this Victorian ring at c 1860's-1880's.
