Nether quartz vs certus. Only mentioning for now
**Gimpansor: ** I'd second that the border on the chiseled and pillar variations should probably be less pronounced to make them look better when stacked. The block version matches the Quartz Block. What's being compared in the image is Vanilla's "Smooth Quartz Block", while our block matches Vanilla's "Block of Quartz".
Certus quartz bricks?
