I wanted to give quartz blocks another go as I didn’t like the original design I did back then; I used a more quartz-like material now as well as pits & dents sometimes found on polished quartz items.
The considered blocks are quartz blocks, quartz pillars and chiseled quartz blocks (and their side/top/bottom variants where applicable)
I also very slightly redesigned nether quartz ore as well.
Spectrum was used to give you those screenshots :
