This fine and impressive gemstone brooch has been crafted in 18k yellow and white gold. This vintage brooch has been modelled in the form of two stylised birds perched on a closed umbrella. The body of each bird is ornamented with an oval cabochon cut chrysoprase. The yellow gold simplified wirework style heads incorporate eyes represented by claw set round faceted rubies, with a combined carat weight of 0.07cts. The heads are further embellished with scalloped white gold wirework designs accented with six claw set eight-cut diamonds.
