This exquisite 18k yellow gold brooch, crafted in 1920 by Gustav Dahlgren & Co. (often listed as Gustav Dahlberg & Co.) in Malmö, Sweden, is a fine example of early 20th-century Scandinavian jewelry design, blending late Art Nouveau influences with traditional symbolism. Design Highlights Form and Motif: The openwork crescent (horseshoe) shape evokes good luck—a common theme in period jewelry—overlaid with geometric frames and beaded edging. At the center, a finely engraved sunflower or daisy-like flower with textured petals and veined leaves features a single natural seed pearl (approx. 4–5mm, good orient and luster). Dangling Elements: Three polished teardrop drops of graduated lengths hang from the base, creating elegant movement typical of pendant-brooches from this era. Craftsmanship: Expert hand-chasing, engraving, and high polish give the warm 18k gold a rich glow. The design shows restrained asymmetry and naturalistic detail characteristic of Swedish gold work in the post-Art Nouveau period. Closure: Trombone-style clasp with extended pin, standard for the time. Dimensions and Weight: Approximately 5–6cm tall (including drops); confirmed weight 8 grams, consistent with solid 18k construction of this delicate yet substantial design. Maker and Provenance Gustav Dahlgren & Co., founded in 1845 in Malmö by Gustav Dahlgren (1815–1875), was one of Sweden's oldest and most respected goldsmith firms, known for high-quality 18k gold jewelry often featuring pearls and symbolic motifs. The company produced pieces well into the mid-20th century, with hallmarks typically including the maker's mark (GD&Co), Malmö town mark (M), Swedish national three crowns, and a date letter (for 1920, "S7"). The visible "18" and "750" marks align with Swedish/continental standards of the era, confirming 18 karat (75%) purity. This brooch represents the refined, wearable elegance of 1920s Swedish jewelry—perfect as a lapel or bodice accent. In excellent antique condition, it is a charming collectible piece from a prestigious maker, ideal for enthusiasts of Scandinavian gold or early 20th-century design.
