Hundreds of sparkling crystals are the keynote of this museum-quality, Romanov-style enameled egg collection named for its benefactor, Tsar Alexander III. The House of Romanov's imperial jeweler's 19th-century creations live on in Nevsky with its rich ebony black enamel and Polotsk set in crimson red. Both are cast in pewter using the ancient lost wax method before the effervescent embellishments are added. Each sits atop tripod legs and opens to hold tiny treasures.
