Brief History of Theodor Fahrner Jewelry

Theodor Fahrner was born in 1859 in Pforzheim, Germany. His father, Theodor, Sr., manufactured and sold rings that memorialized historical events. Young Theodor trained as a metal engraver at the Pforzheim Art Academy where he honed his natural artistic talent and developed a lifelong love of art.

When his father died in 1883, Theodor took control of the company and expanded its production beyond rings to necklaces, bracelets, brooches and earrings. He also pioneered designer jewelry and the use of well-known and respected artists of various disciplines to design jewelry made partly or entirely by machine. Each artist had a distinctive style, and the little ring factory became  was one of the most prosperous jewelry houses in Europe and remained so until the 1950s. Theodor Fahrner jewelry gained international attention when designer Max J. Gradl received a silver medal at the 1900 Paris World Exhibition. Soon Theodor was exporting large quantities of his jewelry around the world, most notably to London and New York City.

Theodor was known for Art Nouveau and Jugendstil (a German style influenced by English Art Nouveau, Japanese prints and Viennese abstracts) designs. Even though his pieces often contained semi-precious stones, he believed that the true worth of any piece lay in its artistic merits. He insisted on mass producing affordable yet exquisite jewelry that people of various economic statuses could enjoy.

In 1919, Theodor died and the firm was purchased by Gustav Braendle. The firm’s name became Gustav Braendle - Theodor Fahrner Nachfolger (German for “successor”).

From the 1920s to World War II, the Art Deco designs reigned. They represented the Jazz Age as they became more geometric. The combination of black enamel, green agate, coral and onyx used by Theodor became signature colors for the Art Deco Era.

In the 1930s, filigree jewelry was introduced, but first German politics, then the war adversely affected production. In the 1940s, the factory was destroyed by a bomb.  After the war, production resumed with a large variety of designs, but the company never regained its pre-war prominence.

In 1952, Gustav Braendle died and his son Herbert took charge of the company with a greatly reduced workforce.

In the 1960s and 1970s, while the company continued producing their traditional styles, many designs were modernized and the jewelry made with stones, both precious and semi. Gold joined silver as the “go-to” metal and both were used to re-create Roman and Egyptian motifs.

In 1979, Herbert died, and Gustav Braendle - Theodor Fahrner Nachfolger was liquidated and most of its records destroyed. However, the jewelry remains in demand today and is sold at high prices.

Tips for Buying Vintage Theodor Fahrner Jewelry

  • Some vendors use terms such as “Art Deco,” “vintage,” and “antique” loosely to attract visitors to their websites. Do not patronize a site if you cannot depend on their advertising.
  • Also, do not deal with a vendor who hesitates to answer your questions or does not answer at all or who does not have positive reviews.
  • If you buy jewelry on sites such as Etsy or eBay leave honest feedback.
  • To avoid getting caught up in a bidding war, determine your top price right at the beginning.
  • If you intend to wear the jewelry, know your measurements: finger size, wrist size, and what length necklace you prefer.
  • Check shipping costs before you commit and also the return policy.

  1. Good day.
    Im Rowena Olimpo from Philippines. I bought this vintage bracelet with hallmatk TF 925 a month ago. Did search for the hallmarks found but nothing really answers my queries about authenticity of the jewel I bought. I will appreciate so much if you could help me/ tell me if this is one of the Great Theodor Fahrner designed jewel? I can send you pictures.
    Anyway thank you so much. Hope I can hear from you.

    • Hello Rowena – and welcome!

      Your hallmark sounds authentic, although I’ve seen some that have the number 925 before the TF. 925 means that the bracelet is 92.5% silver, as you know. His pieces were from the Art Deco and Art Nouveau periods in jewelry and are very collectible. Please send me a picture, so that I can authenticate it further.

      Thank for for reaching out!

  2. Hi, I recently decided to sell a brooch that I have had for a few years and on examining it, I have found the mark of TF in a circle and Sterling, Germany. Looking at your website, it appears to be 1950/60 Theodor Fahrner. It is a small vermeil gold art deco style dog with delicate filigree work. I can find no other animal brooches in this style. Could you please advise me. Many thanks.
