Once the jewel-encrusted playthings of the Russian royal family, the first Faberge Imperial egg produced in almost a century is set to be unveiled in Qatar, its makers said.

Ninety nine years since Faberge made its last Imperial egg, for Tsar Nicholas II, the famous jewel maker will show off its newest creation at an exhibition of watches and jewelery in Doha.

The "Faberge Pearl Egg" features 139 fine white pearls, and more than 3,300 diamonds as well as other precious gemstones, according to the jeweler.

Several Gulf nations have a long history of pearl diving, and Qatar is building an artificial island off its coast named after the precious treasure.
