Dates to the late Edwardian era, circa 1910.
Crafted in solid 14K yellow gold. Does bear hallmarks but as they are difficult to decipher I have also carefully acid tested this piece.
Bezel-set with a polished jadeite cabochon, which measures approximately 10 mm by just over 7 mm, and has an estimated weight of 2.7 carats.
The stickpin measures 2.65” from end to end, with a top portion that measures 0.45” by 0.33”. This piece weighs 2 grams.
Condition is very good, with no damages or repairs.
