I'm working on an amethyst entry for my NatGeo Book on Gems/Minerals/Rocks of the world and had to check how quartz did in #MinCup26. I'm SO late to the news, but yay it won!

#FunFact: amethyst comes from the Greek "amethystos" meaning "not drunk" bc the ancients thought it warded off drunkenness ⚒️
Congratulations to our Mineral Cup 2026 Champion Quartz!

For #MinCup26, we collectively chose a nostalgic beauty of resilience as persistence as our champion. Please celebrate #Quartz, a friend to humans since time immemorial!

To celebrate the win of #quartz in this year's #MinCup26 let me share a very nice quartz crystal I found years ago in Sauerland and now refound when tidying up my Rock drawers ☺️. Size is about 1.5 cm. ⚒️

New stone witch !

The (synthetic) quartz is absolutely vital to all our electronics devices, pacing all processors and watches, and that's what I wanted to represent here !

And also congrats to quartz for winning #MinCup26 !

For this #MineralMonday, I’m continuing to celebrate Quartz’s victory at #MinCup26, and to photograph the quartz specimens in the collection.

Here is a prase flower, a leek-green variety of quartz, with its characteristic slender crystals.

That’s a wrap for #MinCup26!

This year was brought to you by a glorious team of volunteers contributing their favourite mineral facts, drafting blurbs on the side of playgrounds, and debating exactly which photo is both representative and beautiful.

Had so much fun playing #MinCup26, decided to celebrate by going to the ABQ Gem, Mineral & Jewelry Show at the Expo grounds. I was overwhelmed from the moment I walked in the door, but found some cool specimens to buy, including #kyanite and #quartz for the last two winners.

I’m really pleased to see that FINALLY in its 10th year, Quartz has won the Mineral Cup! #MinCup26

Huge thanks to the tireless @mineralcup.bsky.social team who managed the yearly tournament with their usual flair & aplomb, including having to cope with some ridiculous cheating! Take a moment to
Team #Quartz all the way! #MinCup26

Gets my physics vote as 20% of Earth’s crust & representative typical elastic moduli, piezoelectricity & its role in clocks, electronics, GPS, computers!

Quartz has played a huge & varied role in art history since antiquity. Carved, in pigments, canvas prep…
