The egg-shaped clock and its rectangular pedestal are decorated with translucen enamel on a guilloche (1) background. The four-colored gold egg is enameled translucent daffodil-yellow, and is richly set with diamonds. The egg takes the form of a clock with a revolving dial. The body of the clock is divided into twelve parts which are outlined in diamond-studded stripes. The belt of the dial which divides the egg is enameled opaque white with twelve diamond-set Roman numerals and the hours are pointed by the head of an arrow in a drawn bow. The belt revolves around the perimeter of the egg, indicating the time. The diamond clock hand protrudes from an immobile base. A gold key was used to wind the mechanism. The clock is crowned with a delicate bouquet of Madonna lilies, carved from onyx. The pistils of the flowers are set with three small rose diamonds, and the leaves and stems are of tinted gold. It stands on an onyx platform decorated with colored gold scroll mounts, rosettes and the date of its manufacture, 1899, is set in diamonds, and is designed as a vase with red gold scrolls serving as extra supports at either side. The gold rim of the vase is chased as a cluster of roses. The Egg uses the language of flowers, the roses (symbols of love) with lilies (symbols of purity and innocence), and the flowers like torches suggest the virtuous flames of family love. The now missing pendant was made with ruby and ruse-cut diamonds. An early Fabergé photograph is extant showing the ruby and rose diamond pendant that accompanied this Egg. The Madonna Lily Clock Egg was never sold. In 1927 it was transferred to the Moscow Armoury Museum. and is one of the Imperial Eggs kept there.
