#MinCup23 Asparagus has a special place in the heart of us Germans, so I was happy to learn that there is a greenish variety of #fluoroapatite that is called Spargelstein (asparagus stone). Also it shows luminescence under UV light. Very pretty, but...#Zircon is a colorful gemstone which is host matrix for e.g. rare earth elements and uranium and thorium, which makes zircons extremely useful for geochronology. And it can be produced synthetically e.g. for jewellery.

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 🌟

There is a lovely Hungarian poem about a family of clocks. The great-granddad was an hourglass, then there are clock towers, and alarm clocks, and finally the great-granddaughter is a quartz clock, and the line is "she has a grain of old sand in her heart." 🥰

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

As for quartz, here is a Mansi legend about the origin of rock crystals in the Urals. It tells of a chief who built a tower of clear crystal, which a horde of giants shattered, trying to kidnap the chief's daughter. With the help of spirits, the attackers were turned into pillars of stone.

I blogged about the story here

Cinnabar in Chinese folklore was associated with the Vermilion Bird of the South, and one of the main ingredients of immortality pills in Chinese alchemy (ironically, since it's toxic, and if you eat it you'll get the opposite of immortal...)

There is an Oroqen folktale about a hero named Silteken, who goes out to avenge his father's death on a 100-eyed monster. He loses the first fight and dies.

However, his clever horse goes on a quest to kidnap a (willing) princess from her wedding along with her dowry of cinnabar, which can be used to bring the dead back to life.

Revived with cinnabar by his beloved, Silteken defeats the monster.

There is a Japanese folktale about two brothers who go out to gather cinnabar every day from a pond.
The cruel younger brother decides he wants to keep all the valuable cinnabar to himself. He constructs a fake dragon from lacquered bowls to scare his elder brother away from the pond.

However, one day as he goes to collect cinnabar again, the dragon comes to life and swallows him.

We have #Moissanite crystals that formed in other stars! Dissolve some meteorites almost completely, and some of the residue is SiC -these grains have carbon and silicon isotopes produced in red giant stars and supernova; from before our solar system formed.

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:
