This delicate brooch is by the Norwegian designer Marius Hammer.   I found it in a gallery in a place called Ålesund on the NW coast of Norway.  They sold the most beautiful Norwegian enamels.

Marius Hammer was born in 1847.  He was the third generation jeweller and goldsmith in the town of Bergen.  He trained in his father’s workshop, but he had ambition to run something greater than just a small shop like his father and grandfather had done.  He travelled to Hamburg and Berlin in the 1870s to study and brought back new techniques and production methods. He was the first to install gas and electricity into their workshops.  The business grew becoming the largest jewellers in Bergen.  Hammer expanded into the burgeoning tourist market during the 1880s setting up a network of shops along the west coast of Norway and supplying shops across Europe.  In 1885 the company was appointed silversmith to the Prince of Wales and later the German Emperor Wilhelm II and many other Royal Houses of Europe. By 1914 the company employed 130 people making a wide range of luxury goods – Viking ships, spoons, jewellery.  With the outbreak of World War I the tourist market disappeared overnight.  Marius’s eldest son died in 1920 of the Spanish Flu and Marius died seven years later.  The company went bankrupt in 1930.  Today Marius Hammer pieces from the 1900s are sought after works of art.
