Can’t remember what game I played 17 years ago

I recently came to think of an old game I played at a friend's house around 17 years ago. I do not remember what the game was called and I can't find it when searching for it online. My memories of the game is very faint but I want to think it was called something with "Jojo" in it. As for the gameplay; all I remember is that you play as this dark hair kid and you slide down through a dark temple (jungle like) and collect gems of different colour, red, green, black and so on. I think the black ones were the most valuable. The game was in 3D and probably released sometime in the early 2000s because I know we played Rayman 3 at the same time. If anyone has any idea what game this could be I would be very happy to know!
