21w07a Grimstone should look more like dark stone than a cobble of pieces

I appreciate all the hard work being done to make Minecraft better.

As for Grimstone, a mineral which makes up vast lengths of the underground- essentially as a part of the crust- like stone, bedrock or soil it should be solid like they are: homogenous in shape and structure. It's odd that the Grimstone almost appears like bricks or cobblestone because of its amalgam of pieces and shards in the texture, as this gives it either a crumbly, loose appearance or a solid but artificially-wrought one like the bricks and cobblestone I mentioned.

The design itself is done well- it looks like some kind of Minecraftian dark, menacing block. I just don't think it really fits what it's trying to be- a vast layer of the world-crust: homogenous and solid as a whole. This design wouldn't look out of place as part of an old underground ruin or dark Nether dwelling but- again- it doesn't look right as a mineral layer of the earth.

Precedents for mineral homogeneity (minerals being like solid wholes instead of collections of pieces):
Andesite
Diorite
Granite
Stone
Bedrock
Dirt
