Eskolaït from Outokampu mine in North Karelia, Finland
Very rare, although the gemstone has already been described in 1958 by the famous gemologists/mineralogists Kouvo and Vuorolainen! However, you won't run into him quickly!
Eskolaite is a rare chromium oxide mineral (chromium(III) oxide Cr2O3). It was first described in 1958 for an event in the Outokumpu ore deposit in eastern Finland. It occurs in chromium-containing tremolite churning, metamorphosed quartzites and chlorite-containing veins in Finland; in glacial boulders in Ireland and in stream pebbles in the Merume River in Guyana. It has also been recognized as a rare component in chondrite meteorites. The mineral is named after the Finnish geologist Pentti Eskola (1883-1964).
