In 1881, Wilhelm Siebert established the Platinschmelze G. Siebert OHG (general partnership), initially producing cigar boxes and molds. This evolved in 1885 into a platinum refinery for the chemical and jewelry business. By 1906 Degussa (a household name in the German gold business) became a silent partner, completely absorbing G. Siebert by the 1970s. Platinum is 30 times more rare than gold. Annual mining is approximately 133 tons to 1,800 tons of gold. Exceedingly few companies dedicate their operations to platinum. Rarely written about, it occupies a hyper-niche of the precious metals world (that is, outside of Japan where over 90% of engagement rings are Platinum). Sales catalogues exclusively on platinum are as scarce as the metal itself. At the time of cataloguing, no other copies for sale, nor were we able to find a record of this item in OCLC or KVK.
