The Lomonosov porcelain factory was founded in 1744 in Saint Petersburg, Russia. The products were exclusively made for the Russian ruling family of Romanov, and the Imperial Court. Production for sale only started about a hundred years later. Eventually the factory came to be known as the Imperial Porcelain Factory, or IFZ.
Figurines as well as tableware crockery were produced by the factory. The designs were hand-painted and some were embellished with 22 carat gold. Lomonosov porcelain is exhibited in museums and is gaining popularity as a collectable.
Check the language used for the back stamp. Pieces that were manufactured for export will have the stamp in English. Pieces that were made for the Russian market or old pieces may have only the monogram without any wording.
