In 1858, the Leipzig mathematician and astronomer August Ferdinand Möbius caused a sensation when he twisted the ends of a strip of paper and glued them together to form a figure with only one surface and one edge—the Möbius strip. This fascinating mathematical and geometric construct inspired the jewelry manufacturer Guthmann to create this ring. Unlike Möbius’s original, it consists of a narrow band twisted twice, giving it a more delicate appearance. The fascination, however, remains the same: with this ring, too, the surfaces cannot be distinguished according to the criteria of top and bottom or inside and outside.

Making high-quality crafted jewelry affordable for as many people as possible - with this in mind, goldsmith Martin Guthmann founded his jewelry manufactory in 1906. Today, run by his great-grandson in the fourth generation, the family business still produces entirely in the jewelry and gold city of Pforzheim. In the manufactory, rolled, stamped, drawn and cast parts are assembled by hand into small series. Among other things, old jewelry forms and ornaments from the company's own history are incorporated into the design: they are cast and - using historical manufacturing techniques - transferred to our time.
