The House of Fabergé is a jewellery firm founded in 1842 in Saint Petersburg, Russia, by Gustav Faberge, using the accented name Fabergé. Gustav's sons, Peter Carl and Agathon, and grandsons followed him in running the business until it was nationalised by the Bolsheviks in 1918. The firm was famous for designing elaborate jewel-encrusted Fabergé eggs for the Russian Tsars, and for a range of other work of high quality and intricate details.
