So why does Nigredo call Rubedo "Spinel"? Here's a guess:

Spinels are gemstones that were mistaken for Rubies, or Corundum. Hence, Spinels are "false" Rubies.

If Rubedo = Ruby, then Nigredo calling her "Spinel" implies that she is "false", a reference to her belief that Rubedo will betray Nazarick.
