Shungite: The Carbon Rock From Karelia, Fact-Checked

By Digital Towns Crystals ยท Last reviewed October 8, 2026

Short answer: shungite is a black, carbon-rich Precambrian rock from the Lake Onega region of Karelia in northwestern Russia, named after the Shunga deposit. Carbon ranges from about 10% to 98% by weight; the high-carbon type is sold as "elite" shungite and the lower-carbon rock, which takes a polish, as "regular." Claims that it blocks EMF or 5G, or purifies water as a decorative stone, are marketing without evidence.

What is shungite, geologically?

Shungite is a rock, not a mineral with a fixed formula. A Kyoto University research project funded by the Japan Society for the Promotion of Science (KAKEN) describes the material plainly: rocks from near Lake Onega, collectively called shungite after the main deposit Shunga, belonging to the Karelian Super Group, black-colored and dense, with carbon reaching as much as 98 wt% at maximum.

The same project gives the two numbers that matter most to a buyer. Type 1 shungite contains 75 to 98 wt% carbon. Types 2 to 5 contain 10 to 75 wt% carbon and were sampled from the Shunga, Zazhogino and Maksovo deposits. The basalts of the same Ludicovian sequence date to 1.98 billion years by samarium-neodymium analysis, which is where the "two billion years old" line on product cards comes from. The team concluded that the low-carbon rocks probably began as silica-rich sediments carrying organic residues.

So shungite sits in an odd spot: too carbon-rich to be an ordinary shale, too disordered to be graphite or coal. The mineraloids guide covers other natural materials that lack a crystal lattice, and the regional geology fits into the wider Russia origin guide.

What does shungite carbon look like up close?

A 2015 study in Nanoscale Research Letters, available through PubMed Central, compared rock from the Zazhogino deposit with shungite from a commercial filter. It summarizes earlier diffraction work describing shungite carbon as a multilayer globular structure with globs about 10 nm across, built from skewed graphite-like layers. Its own Raman data found sp2-bonded carbon clusters that grew from 9 to 12 nm after heating, with silicon dioxide clusters mixed in. It also found that the high electrical conductivity of shungite belongs to those carbon nanoclusters.

That conductivity is the most useful fact on this page for a collector, because it gives you a real test (see below).

What is the difference between elite and regular shungite?

"Elite" and "regular" are trade words, not geological terms, but they map reasonably well onto the carbon types.

Trade name Geological match Carbon What it looks like How it is sold
Elite, noble or silver shungite Type 1 75 to 98 wt% Silvery black, bright, almost metallic luster; brittle, sharp fracture Small raw nuggets, rarely shaped
Regular or black shungite Types 2 to 5 10 to 75 wt% Matte to satin black, heavier rock texture Tumbles, spheres, pyramids, palm stones, towers

The reason elite shungite is sold as raw nuggets is practical: high-carbon pieces are brittle and break rather than polish, so almost every carved shungite shape on the market is the regular, lower-carbon rock. That is not a fault; it is the material that can be worked. What should raise an eyebrow is a polished sphere labeled "elite," or "elite shungite" offered in large shaped pieces at a regular price.

Watch locality too. The name and the studied deposits are Karelian. A label such as "Colombian elite shungite" describes some other black carbonaceous rock at best, sold under a borrowed name. Material sold as Russian or Karelian with a named deposit is the safer buy.

Does shungite really contain fullerenes?

Sometimes, in small amounts, in some samples. Fullerenes are cage-shaped carbon molecules such as C60, and shungite marketing leans on them heavily. The science is more mixed than the marketing.

A 2011 exchange in the journal Geology, archived by the Indian Academy of Sciences, lays out the history. The first discovery of natural fullerenes in a geological sample was reported in Karelian shungite by Buseck and colleagues in 1992. Ebbesen and colleagues in 1995 speculated that those fullerenes came from a localized event or an experimental artifact. Mossman and colleagues in 2003 did not find fullerenes in the four Karelian shungite samples they tested. The authors of the 2011 reply did find them, but out of twelve Karelian shungite samples they found fullerenes in only three, all of them bright, glassy shungite. A dull shungite with about 60 wt% carbon showed none. The Kyoto project, for its part, reported C60 in Type 1 shungite.

The fair summary: fullerenes have been detected in some high-carbon Karelian shungite, they are not a reliable property of a tumbled stone, and nothing in this literature tests them for any effect on people or devices.

Does shungite block EMF or 5G?

No. This is the claim that sells the most shungite, and it does not hold up.

  • Regulators found no evidence. In a 2023 ruling, the UK Advertising Standards Authority upheld complaints about a teleshopping presentation claiming that a shungite sphere and pyramid clock could block electromagnetic fields including 5G. The advertiser provided no evidence, and the ASA concluded the blocking claims were misleading and that presenting EMF and 5G as harmful was misleading and irresponsible. An earlier ASA ruling reached the same result for other EMF "protection" products.
  • The physics does not work. A radio and avionics engineer writing for NZ Skeptics explains that the only way to stop electromagnetic radiation is a continuous conducting shield, a Faraday cage, and that carbon is a relatively poor conductor compared with aluminium, copper or nickel. In his kitchen test, a phone covered with carbon fiber mat, or with barbecue charcoal, still rang; only kitchen foil wrapped with no gaps silenced it. He also points out that a 2.5 cm pendant covers roughly 1/3,800th of an adult's body area.
  • The premise is not established. The World Health Organization notes that about 25,000 articles on non-ionizing radiation have been published over 30 years, and that current evidence does not confirm any health consequences from exposure to low level electromagnetic fields.

Shungite does conduct electricity, which is where the story starts. Conducting is not the same as shielding a person, and a palm stone on a desk shields nothing.

Does shungite purify water?

Crushed shungite is a real industrial material. The PubMed Central paper notes that shungite is used in metallurgy and water purification and acts as a sorbent, and its own comparison sample came from a commercial filter. That is processed, graded granular media in an engineered system with flow rates and replacement schedules.

A polished sphere or a handful of tumbles dropped in a pitcher is not that. No source located for this guide supports drinking-water claims for decorative shungite, and sellers who make them are making the same kind of unsubstantiated claim the ASA ruled against. If you want filtered water, buy a certified filter; if you want shungite, buy it as a geological curiosity.

How do you tell real shungite from fakes?

Black stones are easy to substitute, and the home tests that don't work guide explains why many popular checks prove nothing. For shungite there is one test with a physical basis:

  1. Conductivity. Set a cheap multimeter to resistance and touch both probes to the stone a centimeter or two apart. Shungite's carbon conducts, so you should get a reading. Obsidian, black tourmaline, black jasper, dyed howlite and resin read as open circuit.
  2. Weight. Shungite is light for its size compared with hematite or black tourmaline. A suspiciously heavy "shungite" sphere is something else.
  3. Surface. Regular shungite polishes to a satin black and can leave a faint gray-black mark on paper or fingers. Glossy, glassy fractures with sharp curved edges point to obsidian.
  4. Shape. A large, flawless carved piece sold as "elite" is a contradiction, since elite material is too brittle to carve.

For the two most common black look-alikes side by side, see obsidian vs black tourmaline, and the full black-stone lineup in the black crystals guide.

How should you care for shungite?

Regular shungite is soft enough to scratch on harder stones, so store tumbles and spheres apart from quartz. Wipe off the fine black dust with a dry cloth; it is carbon and rock flour, and it marks pale fabric. Elite nuggets are brittle and flake at the edges, so keep them in a padded box and handle them over a table.

Shungite in crystal traditions

In crystal traditions shungite is associated with grounding and protection, and it is often paired with selenite in decorative sets. Those are cultural associations; they are not the measurable properties discussed above.

Shopping for shungite: what to look for

Buy shungite for what it is: a dense black rock with an unusual carbon story and a real Karelian origin. Ask for the locality, expect polished shapes to be regular grade, and treat any listing that leads with EMF or water claims as a reason to look harder at everything else it says. A conductivity reading is a fair request for a large piece.

Examples currently in stock, with two black contrasts worth having beside it:

  • Shungite tumbles, spheres, palm stones and towers: regular-grade shapes, including large tumbles and a 40 mm sphere labeled as Russian material; the shaped forms are a good way to see shungite's satin polish.
  • Black obsidian sphere, 50 mm: a 166 g sphere of volcanic glass; set it next to shungite to see the difference between a glassy mirror polish and carbon's softer sheen, then try the multimeter on both.
  • Black tourmaline chunks: raw Brazilian schorl with striated crystal faces, the other black stone most often sold with protective claims, and a useful non-conducting comparison.

Frequently asked questions

Where does real shungite come from?

From Karelia in northwestern Russia, around Lake Onega. The name comes from the Shunga deposit, and research samples come from Shunga, Zazhogino and Maksovo. Shungite sold with another country of origin is a different carbon-rich rock under a borrowed name, so ask for the locality before you buy.

What is elite shungite?

Elite shungite is the trade name for the highest-carbon material, which geologists call Type 1, at about 75 to 98% carbon. It is silvery, bright and brittle and is sold as small raw nuggets. Shaped shungite such as spheres and pyramids is almost always the lower-carbon regular grade.

Does shungite protect against 5G or phone radiation?

No. UK advertising regulators have upheld complaints against shungite EMF and 5G claims because no evidence was provided, and engineers point out that only a continuous metal enclosure blocks radio signals. Shungite conducts electricity, but a stone near a phone does not shield the person using it.

Is it safe to put shungite in drinking water?

There is no evidence that decorative shungite improves drinking water. Crushed shungite is used as industrial filter media, but that is graded material in an engineered system. A polished stone sheds fine black dust, so the sensible approach is to display shungite and use a certified filter for water.

How can I test whether my shungite is real?

Use a multimeter on its resistance setting. Shungite's carbon conducts electricity, so the probes should give a reading, while obsidian, black tourmaline, dyed stones and resin do not conduct. Weight helps too: shungite feels light for its size compared with hematite or tourmaline.
