Native copper in a sedimentary conglomerate. It is proposed that detrital hematite reacts with copper sulfate solutions to reduce the copper and the fluids carry away the iron and sulfur.

The Flemish masters painted on #copper as it provided a smooth, luminous surface that allowed fine detail and durability of the exquisite works, like this self portrait of a laughing Rembrandt. #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology🍎 🔭🪐

Voting for minerals is back this week with the new #OreCup! I am taking my art and physics applications voting scheme from the #MinCup25, but the #OreCup25 is making it hard pitting 2 strong contenders against each other in the first round! Found worldwide Copper & Galena have been used since antiquity (see the woodcut of early Galena smelting via Agricola here). Both used for pigments (as with the copper-based verdigris used in this Van Eyck).

Remember dendrites (from the Greek word dendron meaning tree)? They are tree-like minerals that form under special conditions. There is a lovely dendritic #copper sample on the upper right. Thanks Susie! More in comment 👇🏼 #OreCup25 #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

#Galena is a primary ore mineral for lead.
Nearly every car on the road today, even EVs, have a lead battery for powering accessories.
Lead batteries are the most recycled product (over 99% in the US) and overall lead recycling (76%) is second only to gold.

Naturally occurring pure copper is called “native” copper & is formed in veins & fractures by super-heated mineral-rich fluids often associated with volcanic activity. My sample shown below.

@MineralCup What a wonderful month of friendly contest! Thank you to all who made #MinCup25 possible!
Although I'm still annoyed that beautiful and intriguing #Sapphirine hasn't been back since 2023!

If you haven't voted in the #MinCup25 final yet, my glowy friend #tugtupite needs votes! 2 hours to go!

A few hours are left to vote in #MinCup25 !
Although there are many reasons to pick your favorite one, #color seems to be super important, no? Here is the bracket, with the colors superposed (of course, some minerals have multiple, so I took the snippets from the images on the voting posts or the website).
Don't forget to vote (once)! It's super close now.

Heute ist übrigens das Finale des Mineral Cup 2025, und die Finalisten sind grandios.
Blaues Kyanit trifft auf rosa Tugtupit! Beide sehen toll aus und haben exotische Besonderheiten
Entsprechend knapp ist es in der Abstimmung. Nach mehr als 1500 Stimmen weniger als zehn Stimmen Unterschied.
Hingehen, durchlesen, abstimmen!

With #Kyanite in the final, better purchase your samples today (from your favourite retailer) before the prices go up!
Own the winner for a reasonable cost!

The Montreal Gem and Mineral Show is happening at the end of the month in the main convention center (Le Palais des Congrès).
No guarantee of fantastic #Tugtupite or #Kyanite samples, but many others for sure. There's always a good representation of Canadian and Quebec localities.

Alkali-Nuts is a website devoted to the 400+ minerals found at Mont Saint-Hilaire, including #Tugtupite

Wouldn't it be amazing to have a kitchen counter top made from kyanite?!

While blue kyanite is used in jewelry, porcelain & pottery glazes, plus gets physics points as an index mineral, it’s the extraordinary ‘reindeer blood’ tenebrescent, & phosphorescent tugtupite “King of Fluorescent Minerals” which is also a gem, gaining both art and physics points for me. #MinCup25

Dorky Forbidden Jelly Baby Dioptase needs a votes push to the end! Squishy hug time, get your yummy candy here! 🫂
It's a silly cyclosilicate resident of Oz as seen in the "If I only had an emerald brain" guy in the post above. Under 2 hours left to vote today, and if it gets through, please vote for #dioptase in the final starting right after it as well!

Still please asking #Mosstodon folks + others to consider voting for rock moss of the deserts, Dioptase in #MinCup25, thank you. 🙏 See post above and its replies for earlier photos! 🥦
https://www.mineralcup.org/2025/vote
#TextureTuesday likewise in photos above! It's the #WizardOfOz choice as the "desert emerald", so head down the yellow brick road to the Desert Emerald City for a visit! Team #Elphaba needs your votes to help, #Wicked fans! 😉
2,5 hours left to vote! If it goes through, the finale starts right after at midnight UK time, so please vote for dioptase over Kyanite tomorrow as well! 🍀
((Or tugtupite if it wins tonight :blobcat_party: ))

#Dioptase is an amazing colour-changing pleochroic goddess of a queen that looks as stunning as #Tugtupite - or more so.
She well deserves a crown in #MinCup25!

An international 'crystal water' stone of mystery, it also went by the names of #achrite, #emeraudine, copper emerald or #kirghisite 🥷 👑
An amazing looking explosion of a starburst of a flower shape, The centre a turquoise colour, and the edges of the "blades" or petals of the flower in darker blueish violet colour, behind it darker still.
The lowest part white with flecks of yellow or gold, so it reminds you of space with its haze making for the starburst thought.Very dark green lustrous dioptase crystals that look almost black. This is a night queen that sparkles. And makes for sparks if you heat it up, being pyroelectric AND phleochroic, changing colour depending on how you look at it.
#CopperSilicate (CuSiO3·H2O). Its lustre is vitreous, glass-like, to sub-adamantine, so talking Wolverine shit here, folks. 😅
