Citrine Block - New Building Block & New Nether "Rocks"

This new block is a new crystal-rock that can be found naturally in the nether underground, especially in the nether waste biome. This block also can be obtained by cooking an Amethyst block in the furnace.

This block is for building purpose only, much like basalt and blackstone but also will give nether more underground rocks variety especially for the nether waste biome. This block also can be polished and after that, can be cut to make slab, stair, and wall.
