Oval opal pendant with rose gold chain

This opal and diamond pendant began life as a stickpin from the 19^th century; we remodeled it into a pendant to keep the charm of yesteryear but make it wearable for today.  The oval opal has a brilliant display of greens, blues and yellows, with occasional flashes of red; it is surrounded by 17 old mine cut diamonds with an estimated total weight of .51 carats.  18” rose gold chain included.
