If you browse a shungite catalog you'll find the same rock cut into a dozen different shapes. Each shape has a tradition behind it. Quick rundown of what each one is meant for and where the convention comes from.
Pyramid
The most common form. Egyptian-proportioned (Khufu/Cheops ratio) and Russian-style (taller, more acute apex) are both sold. The pyramid is associated in the broader crystal tradition with energy-focusing, with the apex acting as a point of concentrated effect. Among shungite users, pyramids are the standard shape for room placement, desk work, and EMF-protection siting near devices.
Sizes: 3 cm (small, personal carry / desktop), 5–7 cm (room piece), 10+ cm (architectural / corner-of-house).
Sphere
Favoured for omnidirectional effect, no point of concentration, the influence (per the tradition) radiates equally in all directions. Spheres are the standard for centerpiece display, meditation, and broad-area work. Often sold mounted on a stand.
The Cyril Smith 2016 measurements included a 4-inch sphere; it produced measurable frequency-blocking effects similar to other shapes.
Cube
Grounding, stabilising, in the broader stone tradition, cube shapes are associated with the earth element and structural foundation. Shungite cubes are popular as personal-carry pieces and as paperweights or grounding objects on the desk.
Harmoniser pair (cylinders)
Two small cylinders, typically one shungite and one another stone (often Karelian soapstone or zeolite), held one in each hand. The pair tradition comes from earlier Egyptian healing-rod practices. Among shungite users, the harmoniser pair is used for short meditation sessions or grounding exercises before or after intense computer work.
Pendant / bead necklace
For continuous personal carry. The thinking: rather than placing shungite somewhere in the room, you wear it. The bead-necklace form was tested in Cyril Smith's 2016 study and showed measurable frequency signatures comparable to the larger pyramids and spheres.
Wafer / phone plate
Thin polished slab, often with adhesive backing, designed to stick to the back of a phone, tablet, or laptop. Direct-contact placement on the EMF source. This was the configuration where Smith's measurements showed the strongest blocking effects.
Tumbled chips and raw chunks
Unpolished or lightly tumbled small pieces, typically sold by weight. Used for water preparation (the dominant application), in shoes for foot grounding (a folk practice), in plant pots, or as decorative ground cover in terrariums and aquariums (verify with your specific aquatic species before adding to a fish tank).
Architectural shungite
Large slabs and tiles for floor or wall installation. Used in some Russian sanatoriums, the Marcial Waters chapel, and increasingly in residential applications in Europe and North America. Distinctive matte black aesthetic; very durable.

Editor's note (2026 audit): Smith 2016 sphere/bead/wafer measurement claims pending verification per existing audit on threads 96/101/116/127 Suggested edit: Add Smith 2016 verification-pending notice
Edited 2026-05-03, source audit. Cited sources verified to exist; no fabricated sources detected. Where the audit could directly read the source (live English-language papers, open Russian academic articles), claims were compared against the source content and corrections applied above. Where sources were paywalled or geo-blocked at audit time, bibliographic plausibility was verified via parallel routes (publisher index pages, PubMed/PMC mirrors, cross-citations) but the source content itself was not always directly read. If a specific claim matters to you, click the source link and verify it yourself.
