We have a #MinCup25 champion!! Congratulations, #Kyanite! www.mineralcup.org/2025 After eight years of competing, another few hours to verify votes was nothing, right? Amazing first run, #Tugtupite, and better luck next year.

Ever wonder about who makes Mineral Cup happen? Here’s the #MinCup25 volunteer team! www.mineralcup.org/2025/volunte... Want to join us? We’re always recruiting more volunteers!

America has a new favorite fat bear. Overcoming a broken jaw and an injured paw, Bear 32, also known as ‘Chunk,’ was proclaimed the winner of this year’s “Fat Bear Week.”

As of placing my vote, it looks like only a one-vote margin between the two. #MinCup25 is a close one! If you haven't voted, now is the time! If you have, tell your friends to join!

⚒️ 🧪 A M6.9 earthquake struck Cebu island in the Philippines today, causing at least 20 deaths. The rupture seems to have occurred on an unmapped fault, started below the ocean and continuing to the southwest, passing near populated areas of Cebu. Read more:

#MinCup25 Semifinals 2: Beautiful optics are in play for our last semifinal round between reindeer blood #tugtupite and desert queen #dioptase. Vote: www.mineralcup.org/2025/vote/r4... Results: www.mineralcup.org/2025/results...

hey @nytimes.com: there is no counterpoint here. There are no credible legal experts who would EVER say that the US military has any right or authority to blow civilian craft out of the Caribbean and kill their crews from afar without any provocation. There is no other side to this question.

US court suspends Trump layoff of hundreds at Voice of America reut.rs/3VHWjRR

Can #Dioptase capture the revenge vote from #TeamPervovskite? #Perovskite? The newcomer, #Tugtupite has amassed a huge following as a newcomer. #Mincup25

Hematite wins the arts vote for sculpture too! It’s been used to colour sculpture and within sculpture and jewellery for centuries! Vote hematite! #MinCup25

Not only is hematite one of the oldest pigments known to our species, it’s also carved. Vote for this titan of art history! Hematite was used for amulets for healing & to protect health as it was believed to stop the flow of blood. 🩸 Vote hematite while you still can! #MinCup25

I would say on just the campaigning alone, #Hematite should win this Semi Final round of #Mincup25 but alas it is based on votes. Please vote for #Hematite

Silver hematite iron roses (sculptural, tabular crystals that form rose-like petals & clusters) with prasem quartz (colored green by acicular inclusions of actinolite) forms an ocean floor seascape. Truly #EarthArt. See comment 👇🏼 #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

Fellow Hematitians, lend me your votes! (Unless you’ve already voted. If so, then lend me your lobbying to get MORE votes.) With an hour-and-a-half to go, #Kyanite has a pretty big lead over our #Hematite. Bloodstone Buddy powers, ACTIVATE! #MinCup25 Vote: www.mineralcup.org/2025/vote/r4...

#Hematite Iron Roses are sculptural, radiating tabular crystals that form rose-like petals, and clusters. I wonder if iron roses ever bloomed on Mars? More info in comment. Vote only once: www.mineralcup.org/2025/vote/r4... #EarthArt #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

In the end, while this is a very tough choice between two I love, I vote #Hematite. It turns Mars red, tells the story of the oxygenation of Earth AND possible presence of water on early Venus, crucial in art (ancient & modern) & was my gateway drug into geology. Say YES to the bloodstone! #MinCup25

Have you ever stood on an ancient seafloor bed? This is the banded iron formation (BIF) of Hamersley Range, Australia. Go big #hematite ! Vote: www.mineralcup.org/2025/vote/r3... #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

hematite skeleton, ooh ah! #MinCup25 www.mindat.org/photo-48076....

srsly!!! #hematite #MinCup25 www.mindat.org/photo-213880...

My face, as I campaign for minerals in art, when I see the #MinCup25 voters swayed against mineral titans of art history, like voting for kyanite over 164,000 years of hematite and red ochre in art !? 😱 Give me hematite you rock nerds! Without hematite we couldn’t have this:

I mean, look at these choices: #Hematite: Turns Mars red, key in telling early Earth story #Kyanite Anisotropic & BLUE!!! Blueblueblue! #Tugtupite Piezoelectric reindeer blood! #Dioptase Birefringent GREEN!! Greengreengreen! In the end, there can only be one #MinCup25 champion.

Hematite's red Kyanite's blue Can only choose one What do I do?

You know who’s amazing? The #MinCup25 admins, that’s who! Ballot stuffing makes their lives difficult during this completely fun, silly, educational thing they make happen. Vote for the mineral you love, and vote only once to show love for the admins, please & thank you! Also, vote #Dioptase please

Many people and institutions that fight back are winning. This is a large part of the reason to scorn the people and institutions that have caved. When this is over their lives should be made miserable. More, I mean.

Cheers 🥂 always enjoy it.

As we’re tied with 3 hours to go in this round, the orthorhombic structure of #Perovskite was discovered by Irish X-ray crystallography pioneer Helen Dick Magaw. So a vote for Perovskite is not only a vote for this amazing mineral, but also showers honor on this wonderful #WomanOfSTEM. #MinCup25

How things can change so quickly! #Perovskite is -50 #TeamPerovskite get busy! #Mincup25 Anyone can vote and play. @mineralcup.bsky.social

LeSuPerHero is ready to move mountains for #Perovskite. #VoteForTheFuture #VotePerovskite @lesuper.bsky.uy

Three hours to go! If you haven’t voted yet, we need you! Vote Perovskite! Pre here! www.mineralcup.org/2025/vote/r3... #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

3 hours remaining and only a single vote separates our contenders. Please only one vote per player. We know tight matches are tempting, but go recruit a friend to vote instead! It’s more of a challenge, and brings the fun of delighting in rocks to everyone!

#Perovskite Borg-like crystals can have complex faces. In fact, perovskite has a wide range of morphologies. Lots of twinning, too! Resistance is Futile. #VoteTheFuture #MinCup25 Vote here: www.mineralcup.org/2025/vote/r3... #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

#Perovskite people. It is time to go find some Friend/Colleague/classmate/Team member/Family member or else to cast a vote for Perovskite. Do not wait for the turnover that is imminent at the current vote rate! 4 hours to go. It is time to win it now! #VotePerovskite #TeamPerovskite #MinCup25

#MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐 #perovskite

#Perovskite gets my vote. Look at those cute little dendrites. #tugtupite is cool though so it's a win win round. #MinCup25

Yes, tugtupite is pretty pink and all, but is it as gorgeous as this little iridescent #perovskite dendritic crystal? Vote #perovskite! Vote here: www.mineralcup.org/2025/vote/r3... #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

#Borg rock needs your support. Assimilate #Perovskite today, before it's too late!

This is the quarterfinal I was dreading. I’m all the way in for #Perovskite after its loss to the meat rock (lower case intentional!) in the #MinCup24 finals, but reindeer blood #Tugtupite is so cool, I’m a’feared for the fate of my cubist boi. Vote #Perovskite! Vote Cubular in #MinCup25!

If you like #Perovskite make it a champion and let it shine in #MinCup25. If you don't like it that much make it a champion and enjoy #MinCup26 and more without it. It is easy, one way or another #VotePerovskite 😉

💖 And now I'm required by law to vote for #perovskite for the host. First rock, rains on stars, DEI mineral group, solar power, borg cube, you know the drill. It's pretty and orange and I like it. Host has been campaigning for it since 2022, I think? Vote for his pick for his birthday! #MinCup25

Arguably one of the best parts! I love seeing the creative lengths we'll go to lobby/educate for our favorites. Science lessons, personal stories, persuasive speeches on video--I've learned a lot following #MinCup even casually!
