Are all faberge eggs signed

Not all Fabergé eggs are signed. While many of the eggs created by the renowned jeweler Peter Carl Fabergé were marked with his signature or the Imperial warrant, some were made without a signature, particularly those produced by his workshop or by other craftsmen. The presence of a signature can enhance the egg's value and provenance, but the absence of one does not necessarily mean it is not an authentic Fabergé piece.
