This Scandinavian Modern brooch dates from 1950 and takes the form of a sterling silver and vitreous enamel floral design. The piece depicts two stylized calla lilies with double stems joined by a band near the back. The petals are finished in white engine-turned guilloche enamel with radial linework radiating from the base, while the outer frames, stems, and reverse show a polished silver finish. A pin and roll-over clasp are attached to the back, alongside hallmarks reading Sterling, J Tostrup, and Norway. The item measures 3 cm high, 6 cm wide, and 1.3 cm deep. Designed by Jacob Tostrup, the accessory is suitable for formal or casual outfits, pinned to lapels, collars, scarves, or hats. It comes into its own as a vintage wearable accent for daily attire or special occasions. The construction uses openwork silver elements combined with traditional enamel techniques, creating a clean Mid-Century Modern silhouette inspired by nature. The enamel is intact without chips or losses, and the silver retains a bright reflective surface across all visible components.

Norwegian guilloche enamel jewellery gained international prominence during the late 19th and mid-20th centuries, crafted by renowned silversmiths including David-Andersen and Aksel Holmsen. These pieces feature precise geometric patterns engraved into sterling silver using a rose-engine lathe before being coated with translucent enamel.

The process involves engine-turning or stamping intricate radiating patterns directly onto sterling silver. Layers of pulverized glass vitreous enamel are applied over the metal and fired at high temperatures in a kiln, resulting in a smooth, translucent finish that radiates light through the textured base metal.

Authentic pieces are typically stamped with makers marks, purity hallmarks such as 925S or STERLING, and country of origin markers like NORWAY. Inspecting the enamel under magnification can also reveal clean geometric engine-turning line work beneath undamaged enamel glaze.

A silver and enamel floral brooch can be fastened to the lapel of a tailored blazer, attached to a silk scarf, or pinned on a dark knit jumper to create subtle contrast. It can also serve as a decorative accent on a fabric handbag or coat lapel.

Enamel should be gently wiped with a soft, damp cloth and preserved away from extreme temperature changes, harsh chemicals, or abrasive cleaners. Store the brooch individually in a padded jewellery box to prevent scratch damage to the glass surface and slow silver tarnish.
