How do I keep appearing diamonds?

Hi folks, I have an event which spawns a Diamond on the scene in a random time frame ( every random 2,7 seconds ). If I capture it, it will play the diamond animation destruction and triggers the spawn of an explosion.

Working fine.

The only problem is that after I capture the first diamond, they stop to spawn.

I was wandering if I need to use some kind of cycle/loop or something.

How can I tell the event to restart the whole thing from the beginning after the diamonds is captured?

thanks
