Homeworld forced the clusters together. Sure, the cluster gems may be weak, and humans (Connie, for example) could probably beat it easily. But Peridot is talking about THE Cluster. She also says that "she's going to die here" and that "they'll all be shattered". So I think that THE Cluster is stronger and deadlier than we can imagine.

(Plus, the cluster gems wouldn't fuse by themselves. It was even stated in the show that they were forced together. But I heard some people say that Yellow Diamond forced the clusters together in the first place, but of course, that is only speculation and theories.)
