This RR auction for a Prince Stage-worn Bracelet from Paisley Park's Celebration 2000 says in the description "Prince’s faux diamond bracelet that he wore on stage during a concert at Paisley Park during the seven-day ‘Celebration 2000’ festivities held from June 7 to 13, 2000." The letter of authenticity also says "...while he was onstage at Paisley Park during the first Celebration back in 2000."
It's been 24 years so I admit my memory might have failed me, but I don't remember him having a show at PP during the first Celebration. Only the final closing show at Northrop auditorium. I also looked on princevault and only see that other acts performed at PP. Unless he joined one of them on stage?
