Over 2.5 BILLION years ago this quartz was deposited as sand on the shores of one of the earth's oldest bits of crust. Since then its seen at least 4 orogenic events. Look at it now. Strained and bruised but still quartz. #QuartzNeverDies #TEAMQUARTZ #VoteQuartz #MinCup2018 pic.twitter.com/EiETvkmWBQ
