Antarcticite is an uncommon calcium chloride hexahydrate mineral with formula CaCl 2 ·6H 2 O. It forms colorless acicular trigonal crystals. It is hygroscopic and has a low relative density of 1.715.

Antarcticite (アンタークチサイト, Antākuchisaito), also called 'Antarc', is a Gem in charge of work during the winter. Due to the gem's unique composition, they spend much of the year asleep in liquid form, re-crystallizing when the temperature drops. …

For its occurrence on the continent of Antarctica. A highly hygroscopic mineral. May dehydrate to mesohydride under certain conditions. A synthetic Sr analogue is known. Torii, T., Ossaka, J. (1965) Antarcticite: a new mineral, calcium chloride hexahydrate, dicovered in Antarctica. Science: 149: 975-977.

Named after the continent of Antarctica. Comments: White antarcticite crystals in sealed in mineral oil. Location: Bristol Lake, Mojave Co.,California, USA. Scale: Sample Jar 6 cm. Colorless. Brittle - Generally displayed by glasses and most non-metallic minerals. Acicular - Occurs as needle-like crystals.

Antarcticite occurs in a precipitate from highly saline brines under very arid conditions, and in stratified fresh to brackish salt water columns in onshore blue holes. It is also an abundant component of inclusions in quartz in a zoned mafic pegmatoid.

In a mysterious future, a new life form called Gems inhabit a world destroyed by six meteors, leaving only a beach surrounded by ocean. The 28 active Gems must fight back against the deadly Lunarians who seek to turn the Gems into decorations.

A new mineral, calcium chloride hexahydrate, was discovered in the Don Juan Pond in Victoria Land, Antarctica. The optical properties, chemical analysis, and powder patterns obtained by x-ray diffraction agree with those of artificial calcium chloride hexahydrate. The name Antarcticite is proposed for the new mineral.
