The ground level floor is of Spanish marble, and features a sweeping spiral staircase that leads to the Box Tier level. Four stories above is the dramatic silver leaf ceiling and what has been called a stunning piece of architectural jewelry. Instead of a traditional chandelier, Pelli and lighting designer Francesca Bettridge created a spectacular work of art called “Constellation.” It features Swarovski crystal globes, curved lighting coves and three hundred individual strands of highly polished stainless steel that form a circular pattern 40-feet in diameter. The strands are in graduated lengths, the longest reaching 40 feet, and each is tipped with a handblown, faceted Baccarat crystal globe. The globe on the longest pendant is colored in Baccarat red, the signature of an original Baccarat work. LED lighting is used to illuminate the ceiling and can be changed to nearly any hue to create custom effects and ambience.
