Green agate and marcasite

Unworn silver ring by Theodor Fahrner, circa 1955

In the history of jewellery from Art Nouveau and Art Deco, Fahrner jewellery from Pforzheim occupies a special place. For Theodor Fahrner and later his successor Gustav Braendle understood like hardly any other jewelry manufacturer of the modern age to make artistically convincing designs and quality workmanship the hallmark of their brooches, necklaces, bracelets and earrings. Theodor Fahrner made artists' jewelry affordable by combining modern forms with democratic materials. He did not create individual pieces for a small elite like Lalique or Cartier, but the designs were mass-produced in silver, decorated with enamel, marcasites and occasionally precious stones. Jewelers and department stores throughout Europe sold the jewellery, which Fahrner advertised extensively in journals and magazines: "Fahrner jewellery - based on designs by the best artists" allowed every woman to participate in a modern life full of beauty. Salesmen with large sample cases presented the novelties developed at Fahrner to local jewelers. One such sample case full of unworn Fahrner jewelry had lain untouched in an attic for the last 40 years or more until it was offered to us. It contained samples of nearly every series from about 1919 until the company's dissolution in 1979, most marked with a model number or the "Original Fahrner" seal. The ring here from this collection is therefore unworn and in perfect condition. The model number has been preserved on the original label. The ring is made of sterling silver and shows a green agate in oval facet cut in the center. Metallic glittering marcasite roses accompany the colored stone. Elegantly, the design thereby swings out to the sides and gives the ring a beautiful plasticity. A wonderful overview of the wealth of designs is offered in the catalog "Theodor Fahrner. Jewellery between avant-garde and tradition", edited by Brigitte Leonhardt and Dieter Zühlsdorff, Stuttgart 2005. Fahrner jewellery is often collected.

The citrine, agate, jasper, amethyst and onyx - for the chemist all these gemstones are quite uniform quartz. However, they are clearly distinguished by their color. The color spectrum of the citrine begins with the most delicate champagne tones, shows up now and then honey-colored and extends to a rich tone like sweet Madeira wine.
