This is an antique Victorian-era ring crafted in 18 karat yellow gold by the Swedish jeweler C.A. Sandberg in Helsingborg, Sweden, dated to 1893 based on the hallmarks. The ring features a slender, domed band approximately 3mm wide, adorned with a continuous engraved pattern of stylized wheat sheaves or floral garlands encircling the exterior. This motif, characterized by radiating lines and leaf-like elements, is typical of late 19th-century Scandinavian jewelry design, often symbolizing fertility, prosperity, and eternal love—making it a popular choice for wedding or commitment rings during the period. The interior of the band is smooth and polished, bearing the following hallmarks from left to right: "CAS" (the maker's mark for C.A. Sandberg), a circular symbol likely representing the Swedish national three crowns mark guaranteeing authenticity, "18K" indicating the gold purity (75% pure gold alloyed for durability), another circular symbol (possibly the Helsingborg town mark), and "P6" (the date letter, for 1893. Weighing 4.7 grams, the ring has a substantial yet lightweight feel, consistent with solid 18k gold construction without stones or additional embellishments. The internal diameter measures 18.14 mm, corresponding to a U.S. ring size of approximately 8 (or European size 57), suitable for a woman's ring finger or a man's pinky. The gold exhibits a rich, warm hue with subtle patina and minor surface scratches from over a century of wear, enhancing its historical appeal without detracting from its structural integrity. Overall, this piece exemplifies fine Swedish craftsmanship from the fin de siècle, blending elegant simplicity with intricate hand-engraving. As an heirloom-quality item, it could be worn daily, stacked with other bands, or preserved as a collectible.
