Very nice Victorian 18K yellow gold stick pin in the form of a coiled snake. The head is set with an old European cut sapphire. The engraved detailing is very nice. The snake motif in Victorian jewelry, often used to represent eternal love, became popular after Prince Albert gave Queen Victoria a snake ring as her betrothal gift. Hallmarked with the French "tete de cheval" and an unidentified maker's mark.
Origin: France, circa 1850...
