Damn it! I just finished a week of minerals in Earth Science with my 6th graders.
Wish I had known, but we’ll try to jump in next week.
And #TeamCalcite for me.

@naturaelapides.bsky.socialIt’s the home stretch, #TeamCalcite!
Vote for #Calcite, the only one to produce such a variety of wonders as this delicate little sphere!
@kleinergeologe.bsky.socialTime to translate one of my biggest #TeamCalcite #MinCup2026 Threads to Bluesky.
Think calcite only occurs as bland limestone?
It's also an igneous rock in calcite carbonatites! These can host economic deposits of REE and other rare metal ores. The one shown here was mined for Niobium.
@murduck.bsky.socialCalcite has Iceland Spar, and if you look through it, it refracts so everything is doubled! And it says Vikings used it as a compass and called it a sunstone, which sounds like magic! You can also carve it in its form of alabaster!
GO CALCITE!!!!

@maiainmi.bsky.socialJulienite may change color like Sleeping Beauty's dress.
But calcite is thermoluminescent and sometimes fluorescent. I've always liked calcite, so I'm totally #TeamCalcite. #MinCup #MineralCup2026
