That diamond-encrusted tennis ball, designed by Gitanjali Gems to help launch Wimbledon’s jewelry line, was presented to Venus Williams by Jewelery Marketing Company CEO Nehal Modi last Wednesday, Nov. 14, in New York City.

In case you’re keeping count, there are 4,300 diamonds on that thing!

(And in case you’re keeping track, Venus was also in town to launch her Steve & Barry’s clothing line, EleVen, with a party and a press conference.)
