Which New Year's Eve ball in New York City is covered with Waterford crystal triangles?

The Times Square Ball is covered with Waterford crystal triangles.

The modern ball uses illuminated crystal panels manufactured by Waterford, the Irish crystal company. The panels are arranged in patterned sections and lit with thousands of LEDs, allowing the surface to display changing colors and designs during the countdown.

The ball's materials and dimensions have changed since the first drop in 1907. Earlier versions used simpler construction, while later designs became larger, heavier, brighter, and more technologically complex. The current structure is an engineered geodesic-style sphere rather than a simple glass ornament.

Waterford crystal is sometimes confused with the ball's entire construction. Waterford supplies the decorative crystal panels, but the sphere also depends on a metal framework, lighting systems, and support equipment.
