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.

Just leaving this here. Zircon and monazite. You're not going to see calcite in a sapphire, it couldn't take the heat.

@MineralCup #MinCup2023 because 2023 is the year of #TeamQuartz and not the tasty looking candy-coloured death-cinnabon.
