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

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

Corundum is an incredibly useful material for calibrating powder x-ray diffractometers, and you can get NIST SRM 1976c for this purpose.
it is also heavily used in making high temperature sample holders and about a billion other applications in science and chemistry.

Don’t want to miss a second of the best event in social media, #MinCup23 ? Me either! Starting September 1st, search often for the hashtags #MinCup23, #MineralCup2023, #MinCup2023.
Also, you can make a #List and add @MineralCup to it. You will be notified whenever they post! I used Tooot to create a list, then added Mineral Cup to it. In the image below, you can see my Twitter Tooters list that I have added Mineral Cup to by using the 3 dot dropdown in the upper right corner and selecting “Add to List” (in Toot, I think). Cheers and see you for Mineral Cup in 16 days!
