variety of jadeite called 'Chrome Jade' but its colour, both the emerald green and the black patches, is due to kosmochlor (and its chromium content).

Kosmochlor gets its name from its occurence in meteorites and its greenness.

Meteorite-derived #kosmochlor = Greek for space 'kosmo' & green 'chlor-'. Originally found in Toluca meteorite in Mexico. Extraterrestrial origins, kosmochlor is also found in chromium-rich jade deposits. Chromium leads to bright apple green colour.

All four images from Etsy. As if a totem shaped carving with an Asian stylized dragon, of kosmochlor. It's the size of maybe 4 fingers in height, held in a hand in the photo. Green and darker green leaning toward black in parts. "381.50 Carats Kosmochlor Maw sit sit Carving Dragon" A bright, moss or very bright apple or grass green tumbled kosmochlor stone in someone's hand. It looks hefty and is sort of a vaguely rounded, slightly elongated triangle shape maybe. There are again the more or less black figures making the green stand out even more vividly. Site originally said "931.50 Carats Tumbled Kosmochrol Jade,Maw sit sit Jade,jade albite,jade Burma,chrome jade,green jade." An egg or diamond teardrop shaped tumbled kosmochlor with basically no bits of black, just dark green in places. Vivid green with the apple or bright grass green mostly in the middle. Site's text said "319.50 Carats Tumbled Kosmochlor Maw sit sit Jade, Albite Jadeite, Jade Burmese, Jade Burma, chrome jade, kosmochlor". 273.50 Carats Tumbled Kosmochlor Jade seen more from the side or top. It may or may not be the same as in the second photo, a bit hard to tell by the angles. The hand is now wearing white rubber gloves of some kind.

Apparently, some German Guy decided to dissolve a meteorite in 1897 and got this out of it:

Before it was found in terrestrial deposits, #Kosmochlor was discovered in a meteorite that fell from the skies. More recently it was found in Japan on a boulder of Eckermannite, in a serpentinite outcrop, preserved as a national monument for study, risen from the mantle to kiss the sky.

Kosmochlor was first discovered by dissolving part of a meteorite and its name approximately means "the color* out of space."

"Kosmochlor--the *strange substance* left after the crystallographer Laspeyres dissolved the Toluca meteorite in 1897..."

Either the introduction to this MinCup contender or the start of a cosmic horror story.

#MinCup25 Admin note:

Given the last-minute surge in #kosmochlor votes flipping the match from #kyanite after a 22-hour string lead, we’re going to be auditing QF3. However, offline-life is taking priority.

We’ll make an announcement when the results are certified.
