Well, with the new Nether Quartz Ore, i think they could implement the "Quartz Block", needing 9 Nether Quartz to be crafted (just like Diamond/Gold/Iron/Emerald/Redstone Blocks). The purpose of this, is just to have a new and beautiful decoration block. Builders will be grate =) [Sorry for my bad english, i am from another country]
It's going to be added.
Check out my channel, I'll occasionally upload videos.
