A really cool massive halite crystal with a fluid inclusion!! Halite is a Mineral Cup favourite this year. #MineralMonday #MinCup26 #GeoscienceBluesky ⚒️🧪

Let's not forget that it's Monday, as the final contestants in #MinCup26 face off in nerve-wracking do-or-die showdowns.

For this #MineralMonday, here's a yellow specimen of Uranocircite, a uranium-barium phosphate with a striking yellow color.

Layers of bright yellow sulphur and crystals of celestine. It looks like a (non-edible) piece of cake! #MineralMonday #GeoscienceBluesky ⚒️🧪

It’s #MineralMonday, by the way.

Far from the hustle and bustle of the #MinCup26 (vote for Putnisite), here’s a creamy, yellow and delicate specimen of Cocoinoite, a hydrated uranium phosphate that you’d be wise not to lick!

Mookaite for #mineralmonday.

A form of radiolarite from Western Australia. I got these pieces off the lapidary club's giveaway table.

Sphalerite (var schalenblende) from the Pomorzany Mine, Olkusz, Poland. A favorite desk specimen, given to me by a mine geologist there.
Exhibits typical concentric brown to yellow fine grained mineral layers, along with galena, pyrite. #MinCup26 #MineralMonday ⚒️

🛸 #MineralMonday

Is it a UFO? A flying saucer? Nope - it’s pyrite!

This unusual pyrite nodule from the Tri-State Mining District of Kansas has a distinctly saucer-like shape, with visible crystal forms along its surface.

For #MineralMonday we have the aluminosilicates ... kyanite won last year, but #andalusite is in the mix for #MinCup26!

No pressure.
