Indissoluble bond

Antique knot brooch with old cut diamond in gold, Wilhelm Müller around 1890

The knot motif in jewellery is also often called "lover's knot" in English, because the connection of a couple should be just as firm and unbreakable as a knot. In the middle of the 19th century the knot became a popular motif for brooches and bracelets, and by the end of the century it was impossible to imagine a lady's jewellery box without it. Earrings and rings were also designed in this motif. The present brooch shows itself in the form of a knot, which was looped in the shape of an infinity symbol, a lying eight. Another winding accentuates the center of the design, which is adorned with a glittering old-cut diamond. As the hardest mineral on earth, the diamond is also an ancient symbol of eternity. The brooch has been crafted from 14-karat gold, which has been given a particularly velvety and beautiful shine by an additional fire-gilding process. In its design and materiality, the brooch is a very typical piece of jewellery of the late 19th century. It was once primarily intended to adorn the centre of the collar of a high-necked blouse (cf. the last illustration, from a fashion illustration of 1888). Today, it also works well on the lapel or side of a blouse or coat. Thanks to its timeless design and restrained format, it can also be combined well with a modern wardrobe.

For a jewellery dealer, Berlin was the ideal location. One such trader was the merchant Wilhelm Müller. In 1847, he founded a specialist wholesaler for precious stones, pearls, jewellery, gold and silver jewellery. Most of the creations were manufactured in the branches in the gold city of Pforzheim and in the silver city of Schwäbisch-Gmünd. The head office of the family business was located in the Gertraudenstraße in Berlin Mitte. Miraculously, it survived the destruction of the Second World War and still stands today at Berlin's Spittelmarkt as a reminder of the imperial era. At the turn of the 20th century, the Müller company was the leading jewellery trade and was known beyond the borders of the capital for its high-quality goods.
