Red Rocks in Cutter's Cry?

[LuckyFish]

First time posting a new thread! Yay!

Going through Cutter's Cry, I couldn't help but notice how the last part starts to become full of glowing blue rocks and vents of blue steam. We know this is the telltale sign of raw Ceruleum, and it makes sense. The entrance to Cutter's Cry is in the Northern part of Central Thanalan, so this part probably goes well into the Ceruleum-ruch Northern Thanalan.

But what are the RED rocks?

The blue Ceruleum gradually gives way to a glowing red rock that isn't as dangerous (doesn't act as a hazard) but I can't help but feel like it might be important somehow. It's not your standard red crystal, as no other crystal glows quite the same shade. What is this stuff?

Could be the same stuff as the lamp posts inside the Dravanian forelands mountain ( forgot the name) is made of.

Im thinking naturally, pure fire crystals. We are going quite deep so perhaps crystals get purer the closer we get to the core of the planet

I was thinking healthy fire crystals, as well. A lot of northern Thanalan is corrupted (aka over-aspected) crystal ("Dalamud's Talons"), but this is less orange by far. This could have just been a deeper, more sheltered area. The only crystal-like texture that's like it is the wonky dark matter formation out in Boulder Downs, but that seems unlikely in a cave.
