What was inside the first Fabergé egg?

The first Fabergé egg was commissioned by Emperor Alexander III as a gift for his wife. The egg opens to reveal a gold yolk, which then opens to reveal a gold hen. The hen then opened to reveal a replica of the Imperial Crown containing a ruby pendant within it. Both the crown and pendant have been missing for many years and are only known about because of an old photo. You can find a selection of Fabergé on 1stDibs.
