Fabergé eggs continue to delight fans with their remarkable craftsmanship nearly 100 years after the fall of the Romanov dynasty.

While only 50 were built before 1917, Rolls-Royce says these “exceptionally precious creations are some of the most valuable and coveted objects ever to have been made.” Since the eggs are synonymous with wealth and attention to detail, Rolls-Royce and Fabergé have teamed up to create an all-new egg for “one discerning patron.”

While the company declined to name the buyer, Rolls-Royce says the design of the egg was created by their designers Stefan Monro and Alex Innes. It was then rendered by Fabergé lead designer Liisa Tallgren and brought to life by a team of seven craftspeople.

While Fabergé eggs continue to be popular, Rolls-Royce says the Spirit of Ecstasy egg is only the “second to be commissioned in the ‘Imperial Class’ since 1917 – a category reserved only for Fabergé’s most illustrious creations.” As a result, the egg is truly remarkable as even its base is constructed of engine-turned 18 karat white gold which has been hand-engraved and covered in a purple enamel guilloche.

The egg’s shape is created by “arms of rose gold” which are covered in nearly 10 carats of round white diamonds. They eventually give way to purple amethysts which weigh over 390 carats and were specially selected for their “color saturation and quality.” These unique elements form a protective cocoon around the Spirit of Ecstasy which was created from hand-sculpted frosted rock crystal.

Since the egg is part of the Imperial Class, it has a ‘surprise and delight’ feature just like its predecessors. In this case, a lever at the base of the stand ‘opens’ the egg and frees the Spirit of Ecstasy from her high-end prison.

The egg was unveiled at the House of Rolls-Royce in Goodwood earlier today and it will be shown in the window of Fabergé’s store in London this holiday season. It will then be delivered to its owner who is described as a “great collector of both brands.”

In a statement, Rolls-Royce CEO Torsten Müller-Ötvös said “’The Spirit of Ecstasy’ Fabergé Egg was born from an intrinsic desire to further the realms of Bespoke personalization. Responding to the continuing demands of patrons in search of unique and cherished possessions, a designer at the House of Rolls-Royce sketched an egg, igniting a fascination that will undoubtedly become one of the most collectible items of modern times.”
