This small yet bold quatrefoil shape pendant with calibre cut rubies (approx. .20 carats) and an old mine diamond center(approx.23 carats) is reminiscent of the gothic shape. Although not from the gothic period, this lovely vintage piece most probably from the 1920's has beautiful detail which is finely crafted with the invisibly set rubies and the finely rendered quatrefoil design in 14 kt. yellow gold Although it was a stickpin in its first life, I think it makes the perfect necklace to wear alone or layer with others at 16 inches in length. Not marked but tests 14 KT.
