Dates to the Edwardian era, circa 1910.
Crafted in solid 14K yellow gold and hallmarked as such upon the clasp. Also bears the hallmark of an iron cross within a circle - a fairly prolific maker, but one I have never been able to identify.
Gorgeous fretwork design, with two interwoven bands of gold surrounding the 9.75 mm by 5 mm cabochon of Amazonite.
The stickpin measures 2.75" from end to end, with a top portion that measures 0.74" by 0.55". This piece weighs 2.3 grams.
Condition is very good, with no damages or repairs. Very minor bends to pin stem.
