The egg is made from gold with translucent lime yellow enamel on a guilloché field of starbursts and is in reference to the cloth-of-gold robe worn by the Tsarina at her Coronation.
[citation needed] Fitted inside a velvet-lined compartment is a precise replica, less than 100 mm (4 inches) long, of the 18th-century Imperial coach that carried the Tsarina Alexandra to her coronation at Moscow's Uspensky Cathedral.
The miniature is complete with moving wheels, opening doors, actual C-spring shock absorbers and a tiny folding step-stair.
The Russian nobility and guests gathered on the Eastern Orthodox day of Dormition, the death of Mary, inside Uspensky Cathedral for the actual coronation.
Upon the fall of the Romanov Dynasty, the egg was confiscated by the Provisional Government in 1917 and was listed among the treasures removed from the Anichkov Palace.
The egg was purchased in 1927 by Emanuel Snowman for Wartski a family-owned firm of art and antique dealers in London.

"[citation needed] In a 2013 BBC Four documentary, Vekselberg revealed he had spent just over $100 Million purchasing the 9 Fabergé eggs.
The replica was produced by design studio Vivian Alexander, popular for recreating famous items of jewelry for public and private purposes.
