Edwardian Yellow Gold and Blue Sapphire Stickpin

This is an antique stickpin, likely dating from the Edwardian era (early 20th century). The piece features a decorative head crafted in yellow gold, characterized by fine openwork filigree and scrollwork motifs that frame a central square-cut blue gemstone. The stone appears to be a synthetic or natural sapphire, held in place by four distinct corner prongs. Below the stone, a small decorative leaf element adds aesthetic detail. The head is securely mounted atop a long, slender gold-toned pin approximately 2.5 to 3 inches in length. A hallmark or maker's mark is visible on the upper portion of the pin shaft, though it is not fully legible from the image; it likely indicates the gold purity (such as 10k or 14k) or the manufacturer. The construction shows high-quality craftsmanship consistent with late 19th or early 20th-century jewelry production. Regarding condition, the metal shows a mild age-appropriate patina and light surface scratches. The pin remains straight, and the gemstone setting appears secure without visible chips to the facets. The overall aesthetic suggests a piece intended for formal gentleman's attire or as a lady's lapel accessory.
