This is a truly exceptional example of a classic ring style. Constructed in 18k yellow gold and platinum, it centers on a vivid, rainbow-flecked natural opal that dances with flashes of blue, green, gold, and a luscious pink. The oval opal is surrounded by a frame of nicely proportioned old European cut diamonds that are set with demi-bezels for a smoothly scalloped edge that sits low to the hand and never snags. The opal weighs .80 carats, with .75 total carats in fine antique diamonds. Ca. 1915, current finger size 6.5.
