New Year’s Eve ball unveiled with whopping 2,688 new sparkling crystals before blockbuster party

The final glittering crystal triangles that make up the Times Square New Year’s Eve ball were installed Friday — revealing the new facade of the iconic geometric dome that will ring in 2025.

Rapper Pitbull carefully lodged the last triangle in its place at the unveiling, which marked the first time in a decade that all 2,688 pieces on the ball were replaced at once.

It will be the last time the 11,875-pound pound ball will make its descent atop One Times Square — the massive structure will be retired following this year’s New Year’s Eve party, along with its accompanying countdown numerals, and displayed in a museum planned for 2025.

But don’t fret: a new ball and numerals will be raised for next year’s celebration.

In the weeks before the unveiling, lucky visitors had the chance to install the new 2025 crystals on the ball themselves — and take home one of the old triangles that were being replaced.

The 2,688 crystal triangles vary in size, and range in length from 4 3/4 inches to 5 3/4 inches per side.

The new crystals showcase two special patterns: the 2025 design features long linear cuts with a circle near the top representing the 139′ pole and the iconic building famous for the ball drop celebration as an ode to One Times Square’s legacy.

The Ever Crystal design highlights the future to come and consists of three pairs of interlocking rings surrounded by diamond-shaped facets that provide the setting for the letter E, symbolizing unity and enduring love.

The New Year’s Eve ball was first dropped in Times Square in 1907 and was much smaller than the behemoth unveiled Friday.

The 700-pound, 5-foot diameter ball was made of iron and wood and featured 100 25-watt light bulbs. Six newer versions of the ball have been featured in the century-plus since that first celebration.
