This is because eggs are related to Russian traditional religious customs, and they are necessary for some religious festivals, especially for Christians at Easter. People regard eggs as idols, protect God and keep them at home.
Russians also welcome newborn babies with eggs. Russian jewelry has a long history. The first royal Easter egg was born on Easter in 1885. At that time, in order to comfort Queen Maria, who was married from Denmark, Tsar Alexander III specially made an exquisite egg for the Queen as an Easter gift from Faberge Craft Company of Royal Jewelry Design Company. Faberge used his intelligence to turn an ordinary egg into a gorgeous legend.
