Cassiterite : SnO₂, Pyrite : FeS₂
	Ivigtut Cryolite deposit, Ivittuut (Ivigtut), Arsuk Firth, Arsuk, Kitaa (West Greenland) Province, Greenland Dark brown, twinned cassiterite crystals with pyrite. The specimen was originally covered with fluorides and siderite, but I etched these minerals with Hcl to free the cassiterite crystals. The specimen is in the microcollection of OT. Ljøstad.

Chiolite : Na₅Al₃F₁₄
	Ivigtut Cryolite deposit, Ivittuut (Ivigtut), Arsuk Firth, Arsuk, Kitaa (West Greenland) Province, Greenland Fragment of transparent ice-like monograin of chiolite. When seeing on the specimen begin to understand, that name for chiolite(=snow-stone from Greek) was mixed up - this mineral much more similar to ice, than cryolite (=ice-stone from Greek). But on the type locality chiolite really is similar to dirty snow in March... Associating mineral is ...

Chiolite : Na₅Al₃F₁₄
	Ivigtut Cryolite deposit, Ivittuut (Ivigtut), Arsuk Firth, Arsuk, Kitaa (West Greenland) Province, Greenland An EXCELLENT, lustrous, translucent and blocky specimen of the VERY RARE mineral chiolite from Greenland. Chiolite is related to cryolite, but is much rarer and only occurs as massive material. This is a valuable piece of gem rough weighing 28 grams. 3.6 x 2.1 x 1.7 cm
