German c.1920 Theodor Fahrner silver necklace with double-sided enamel panels and onyx beads

From the Art Deco period, c.1920, this necklace by German jeweler Theodor Fahrner is crafted in silver with double-sided enamel panels in black, red, and aqua, punctuated by glossy onyx beads. Sourced in England, it shows the brand’s signature balance of clarity and surprise: color fields are cleanly divided by silver lines to form a crisp geometric composition, while the onyx links add rhythm and movement. It feels modern and wearable, yet unmistakably of its time.

Theodor Fahrner (1859–1919) was born in Pforzheim—the “Golden City”—where he trained as a steel engraver before taking over his father’s ring workshop in 1883. His firm became known for Jugendstil jewels in enamel, pyrite, and semi-precious stones inspired by natural forms and animals, and for collaborations with designers such as Max J. Gradl. A silver medal at the 1900 Paris Exposition brought international attention; in the early 20th century the company registered the TF trademark and began exporting to England, later embracing the sharp geometry of Art Deco. Comparable designs are published in Fahrner Jewelry: Between Avant-Garde and Tradition.
