Necropolis - Cluster jewel as a base type

I just checked and I was surprised that cluster jewel is not one of the base type available into the necropolis. I mean, there are a few corpses for specific bases (like the stygian belt) so I was surprised that there was no base for this type of 'jewel'.

It would provide an alternative to having to get them through Delirium, especially since other content from Abyss can be crafted out of the graveyard.
