A note on terminology and provenance, since "Russian shungite" is the marketing label and "Karelian shungite" the more accurate one.
The main commercial deposit is Zazhoginskoye, in Medvezhyegorsky District on the northwest shore of Lake Onega, near Shunga village. The village gives the rock its name. The whole area is part of the Republic of Karelia, formerly the Karelo-Finnish SSR, in the Russian Federation today.
The cultural-geographic part: Karelians are a Finnic people, ethnolinguistically related to Finns. The Karelian language is in the same Uralic family as Finnish, not Slavic. Karelia as a region straddles the modern Finland-Russia border. Russian shungite vendors usually downplay this, but if you want to be precise, "Karelian shungite" is more honest than "Russian shungite."
The political part: The Zazhoginskoye area was always on the Soviet/Russian side of the pre-WWII border. Finland did occupy it briefly during the Continuation War (1941-44) and held the eastern shore of Lake Onega until 1944, but lost it back at the Moscow Armistice. The territories Finland actually ceded in 1944 were further west and south: the Karelian Isthmus, Ladoga Karelia, Salla, and Petsamo. Those are the famous "lost Karelia" of Finnish memory. Shunga is not part of that loss. So when people say shungite was "stolen from Finland," that is not quite accurate at the legal-territorial level.
Where it gets interesting:
- The Karelian heartland on both sides of the border shares the same Precambrian shield geology. The Onega palaeoproterozoic basin extends well beyond the shungite outcrops.
- Finland has comparable Precambrian formations but no significant shungite deposits, which is part of why the rock is treated as a regional curiosity.
- Melezhik 2004 (cited in the literature thread) goes deep on the geology of the Onega basin and the shungite-forming process. Worth reading if you want to understand why this specific Karelian basin and not the Finnish side.
If anyone has Finnish-language or Russian-language sources on the cultural framing, drop them. The English-language internet is largely vendor marketing, so primary sources help.
