It's the #MinCup24 finals! There were ups and downs, but my favorite Rhodochrosite has made it to the finals! Please vote for this lovely pink mineral that has inspired many legends 😊

FINAL MATCH

Rhodochrosite vs Kyanite
Mika McKinnon (Mineral Cup)
#minerals #mincup24

For today's round of #MinCup24 the storytelling vote goes to copper 😄

It features into some of my favorite folktales and legends:

- The City of Brass (1001 Nights), where djinn are captured in copper vessels and adventurers explore a magical city

- The Copper Forest, a Hungarian folktale where one of the stereotypical three princesses is actually in love with the enemy king, and finds a way to marry him in the end

It’s Mineral Cup time! See below for the bracket. Who will be crowned king of the crystals this year? *You* might think this is low stakes, but if so you clearly haven’t met many geologists…

So, it's September, and it's time for the Mineral Cup! My favorite time on Mastodon 🥰

Incidentally, it's also the weeked of the Budapest Mineral Show. Where people can vote for Mineral of the Year 2025 and Fossil of the Year 2025 😊 3 candidates each. The geologists at the booth are lobbying hard for their favorites. I was won over by the opal lobby. And got a button!

(Also pictured is a pink opal bracelet. Because pebbles!)

They just announced Mineral and Fossil of the Year 2024 in Hungary! Mineral is corundum, and fossil is the woolly mammoth.
Also, Mineral Resource of the Year will be copper.

Yay!

Loot from today's mineral fair. A very pretty agate pendant, a charoite pendant, and some carnelian pebbles because the archeologist in me loves carnelian. 🥰

For today's #MinCup23 match I already posted folklore (see retoots), but I just wanted to add that topaz is also a card in the Telluric Tarot deck, and I will never stop gushing about this deck 😄 Topaz is the Strength card, by the way.

Today's #MinCup23 match is calcite vs opal. This'll be a thread.

Calcite reminds me of a story from Costa Rica. A chief called Nandayure owned a magic wand that could make disappear anything that contained calcium. One day he saw his people dancing, wearing lots of white body paint, and grew so angry at the decorations he aimed the wand at them. You know what else has calcium? Bones. Oops.
(He managed to reverse the spell by destroying the wand)

Today's #MinCup23 match is corundum vs lawsonite.

*Cracks knuckles*

I'm voting corundum, because folklore (and because as a kid I had a book on gemstones, and padparadscha seemed so magical).

I'm going to make this a thread, because rubies and sapphires figure into a whole bunch of tales and legends.

I don't have anything folkloric to say about today's #MinCup23 match, but they are both featured in the Telluric Tarot by Lunaria Gold (my favorite deck ever).

Crocoite is 7 of Wands, dioptase is Page of Cups.

Today's #MinCup23 match is stibnite vs sodalite.

Stibnite is also known as kohl, used as an eyeliner since Ancient Egypt.

There in an Egyptian folktale where a dervish puts magic kohl on the eyes of a young man, rendering him invisible so he can sneak into the king's palace to see a princess.

A wily old woman catches the trespasser by burning buffalo dung - the rancid smoke makes the guy tear up, and the tears wash the magic kohl from his eyes. Oops.

There is a "Greek myth" going around in esoteric circles about Dionysus and Amethyst, but it's actually a 17th century fakelore invention. Probably based on this belief.

Fun fact, the Hungarian version of D&D had gemstone-based magic, and lucky characters got to use amethyst to purify alcoholic drinks 😄

Amethyst is a purple variety of quartz whose colour is caused by iron replacing silicon and then exposure to gamma radiation. Its name comes from the Greek amethystos (not drunk) - it was thought that amethyst could cure drunkenness 🥴 #TeamQuartz #MinCup23 #minerals #mineral @MineralCup 10/?

Quartz often contains inclusions of other minerals, such as this rutilated quartz glowing in the morning sunshine in the NHM London Mineral Gallery 🌟

A quartz oscillator is used to regulate time inside most watches and clocks. This is because quartz is piezoelectric, which means that when it’s squeezed, it generates an electric current. This also works the other way round too: when an electric current passes through it, it vibrates at a certain frequency. The quartz oscillator is circled in the picture below

Art lovers! Vote quartz! There's a long history of quartz being carved into beautiful pieces.

Have you ever visited a museum or gallery and seen something carved out of rock crystal? Well that's just a colourless variety of quartz. This is a Fatimid (#Egyptian) jug carved from quartz, late 10th to early 11th century

I know many people are upset ice didn't make it into #MinCup23. Well, why not vote #TeamQuartz? The oldest name for quartz is the Greek word κρύσταλλος (kristallos) which was first used 300-325 BCE. Kristallos means cold - it was believed that crystals were a type of ice that couldn't melt because it was made by the gods ❄❄❄

A fact for the #etymology nerds! The word quartz describes one of its physical properties. It comes from the German word "Quarz" which has origins in various Slavic words for "hard" (e.g., Czech "tvrdý", Polish "twardy", Serbian/Croatian "tvrd"). Quartz is a pretty hard mineral as it's 7 on the Mohs hardness scale

#mineral #minerals #MinCup23 #TeamQuartz @MineralCup 2/?
The Mohs hardness scale. The left column shows the hardness of minerals: Talc is 1, gypsum is 2, calcite is 3, fluorite is 4, apatite is 5, orthoclase is 6, quartz is 7, topaz is 8, corundum is 9, diamond is 10. The right hand column shows the hardness of various everyday objects: A fingernail is 2.5, a copper penny is 3.5, a knife/glass plate is 5.5, a steel nail is 6.5, a masonry drill bit is 8.5.

Cinnabar has a slight lead over quartz and I'm not happy about that! This is the start of a *long* thread for #TeamQuartz which I'll be updating throughout the day.

Quartz is my all time favourite mineral. Despite its simple formula (SiO2), it can be found in a variety of colours and morphologies 1/?

C'mon folks, go to #MineralCup at https://www.mineralcup.org/2023/campaigns/round-1-match-2 and put your vote in for #Quartz! Quartz is the working stiff of #Minerals, the everyman, it's the Joad family of minerals, basically. Sure #cinnabar is pretty, it's splashy, and is an important mercury ore mineral, it's worthy, but can you count on it when the chips are down and you need to build a road, or make a sandcastle? Why do these people hate #sandcastles? That's like hating #kittens. #MinCup23 #TeamQuartz

Today's #MinCup23 vote is between cinnabar and quartz. This is a tough one! Going on folklore, both have a whole lot to offer.

I'll make this a thread and share some stories.

Sapphirine's type locality is in western Greenland, south of Nuuk, which is where the mineral was discovered in 1809 by Karl Giesecke.

It was named due to its blue color being similar to sapphire, a different, associated mineral (#corundum, aluminum oxide).

An amazing amount of information can be found about #sapphirine at MinDat:
https://www.mindat.org/min-3531.html
a non-profit mineral data base founded in 2000 by Jolyon Ralph (who is on Mastodon at @jolyon).
