Victorian Opal Ring with Diamond Halo in 14K Yellow Gold.  This cabochon cut opal ring features a flirty, iridescent stone surrounded by a halo of rose cut diamonds on a 14k yellow gold band. This adorable piece of jewelry was created in the Victorian era (1830s 1900s) and has a fun-yet-sophisticated profile. The opal reflects hues of pastel blue and champagne pink. The gallery of the ring is shaped similarly to a small golden crown that holds the .45ct primary stone and accent diamonds. Gorgeous!
