Ivigtut was the world's only mine for cryolite. Cryolite was used [as early as the nineteenth century] as a flux for processing bauxite in aluminum production and before that to produce opaline glass. The mine closed several times in the 1960s, 1970s & 1980s but production continued - dumps were dug out, the mine reopened to excavate low-grade ore and finally the pier, made from 'waste rock', was removed and processed.

Most of the interesting sulphides are known from small spots in polished ore sections (galena is a good indicator mineral!). In cryolite only pyrite, galena, sphalerite and chalcopyrite are common. Molybdenite chiefly occurs in the host rock, enclosing the cryolite ore body.

Ivigtut is a spectacular source of rare minerals, but optimistic erroneous identifications abound. Cryolite crystals are for all practical purposes rarely available - they were collected a long time ago and everybody wants them. Virtually all specimens came from two, large pockets. By far most of the 'Cryolite crystals' I see are thomsenolite, pachnolite, ralstonite or something similar, subject to optimistic interpretation. Incidentally, thomsenolite does occur as parallel grown very large pseudo-cubic crystals and/or crystals with strong basal cleavage that make good cryolite imitations!

Particularly European dealers in the 1980s offered prosopite crystals, more often than not accompanied by assurances they had been 'x-rayed' and were thus correctly identified. Bogus! Most - most, but not all! - of these are microscopic crystals of ralstonite, coating the interior of druses in massive blue prosopite. Obviously, if you remove the interior of a druse with a dental drill, and look for prosopite on your X-ray machine, you are going to find ... prosopite! This comes from the matrix, not the crystals. Prosopite crystals are quite rare, invariably 'flattened six-sided' (say, like a double arrowhead), whereas ralstonite is cubic (and in this association, usually octahedral).

[Many uninformed people claim Ivigtut as the locality for their specimens merely because it is the most famous locality there.] Villiaumite ... when I see this, I usually just walk away from the perpetrator. villiaumite is sodium fluoride, comes from Greenland, and thus must be from Ivigtut 'where all the fluorides come from.' I doubt anybody would accept a claim of benitoite [should be from Gem Mine, San Benito Co., California] as coming from the Stewart Mine near Pala, San Diego Co. [lithium pegmatite with tourmaline] merely because both produce interesting silicates? In Greenland, villiaumite occurs exclusively at Kvanefjeld in the Ilimaussaq alkaline intrusion near Narssaq ... a bit further than San Diego Co. is from San Benito Co.
