Kreuter & Co.
Kreuter & Co was founded in 1842 and worked with other famous jewelers in Germany such as Robert Koch (since 1879) to provide high quality jewelry of excellent craftsmanship. The craftsmanship from Koch lead to Kreuter's success and noble customers from Europe and Russia began to frequent Kreuter. In fact the partnership with Koch helped the two companies produce a combined 700 crown jewels. Kreuter and Co was eventually sold to Hanau companies and the name disappeared in 1984.
