Royal Granite is a mod that adds 4 new types of granite:

1. Luxullianite

-Spawns next to granite and gravel at low elevations in The Overworld.

-Can be crafted into Luxullianite Pillars.

-Spawns in rare clusters scattered across The Nether.

-Can be smelted to create Crushed Luxullianite, which is used to craft all the glass blocks added by this mod, as well as arrows.

-Based on a real life rare type of granite containing Tourmaline.

2. Blood Granite

-Spawns in small clusters across The Nether.

-Can be crafted into stairs, slabs etc.

3. Black Galaxy Granite

-Spawns at low elevations in The End

-Shimmering Black Galaxy Granite is a glowing variant that is more uncommon.

4. Van Gogh Granite

-Spawns in Savanna & Jungle biomes.

-Lava flowing under a Lapis Lazuli Block with Luxullianite below will create Van Gogh Granite.

Automation:

Royal Granite also adds more block generators to the game, similar to vanilla cobblestone/stone/basalt generators to make several more farmable blocks.

Once you have obtained all of the 4 granite types added by this mod, you can craft The Granite Agglomerator. When lava flows below a Granite Agglomerator, blocks will be generated depending on what block is below the lava. Below is all the stone generators added by this mod.

These new granite types (many of which are easily farmable) are also good for decor and building.

Other Notes:

-This mod is free to be used in modpacks.

-I will port to newer versions in the near future, but will not backport.
