A lace pin is a small piece of antique jewelry, also known as a fichu pin, used to secure a triangular scarf (fichu) or lace collar to the neckline or shoulder area during the Georgian era. These pins typically feature a decorative centre with gemstones, hairwork, or other embellishments, and are characterized by their small size and use of a traditional "C" clasp and tapered pin for fastening.
