How, you might ask, does a perfectly formed #zircon get into a sapphire?
Sapphire melting temp: around 2030 °C. (wikipedia)
Zircon melting temp: high melting point (over 2500°C). (https://www.ga.gov.au/education/classroom-resources/minerals-energy/australian-mineral-facts/zircon)
Tiny zircons can withstand a lot of what makes and destroys other minerals.Vote: https://www.mineralcup.org/results/round-4-match-1

Currently a competitor in #MinCup23, #Quartz is a #crystalline form of silicon dioxide (#SiO2) with a trigonal #crystal system that, ideally, results in the growth of a hexagonal column with pointed ends, but nature rarely allows this, as this #Macro #image demonstrates.
