The gold for this delicate ear stud in a flat shell shape was extracted from German rivers without the addition of mercury or cyanides; a mechanical channel wash is sufficient to separate the material from the gravel and sand. The embossing process gives the soft fine gold more hardness, while the shell shape of the pendant gives the material additional stability. The surface of the ear stud is brushed, the plug is made of stainless steel.

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.
