Impossible Blackholes

Impossible blackholes are super rare phenomena that appear at the edges of dimensions. The occurrences only happen when 2 dimensions intersect each other, forming a deadly bridge that can suck in a living Dimensionere and spit out their dead body on the other side. The blackholes emit a radiation that slowly crystalizes into a harden gem when in contact with extreme heat, extreme pressure, and a rocky surface. This is crucial to the formation of Essence Gems.
