Antique five stone opal ring with English hallmarks accented by rose cut diamonds set in 18k gold. The ring features nice matching white opals with red and blue fleck, set with small rose cut diamonds. The ring has nice filigree sides. The ring is nicely matched and has nice graduation. On the inside is an English stamp and P.CH (likely a maker mark). The ring is a size 5.5. The ring is in nice condition, and would look lovely alone or with a stack of other five stone rings.
