Kammererite is the purple to magenta, chromium-bearing variety of clinochlore, a chlorite-group mineral. Its most useful identifying trait is a soft (Mohs 2 to 2.5), pearly, platy habit that splits into thin plates, often on green serpentinite. Crystal traditions link it with the Third Eye and Crown chakras.
Most commonly confused with
- Lepidolite: Lepidolite is a lithium mica that is usually lilac to pink and commonly occurs in pegmatites, not chromium-rich ultramafic rocks.
- Charoite: Charoite is typically massive with swirling violet patterns, while Kammererite is more often platy, flaky, or micaceous.
- Sugilite: Sugilite is generally denser-looking and massive to granular, lacking the chlorite-like perfect cleavage of Kammererite.
- Purpurite: Purpurite is a manganese phosphate with a duller earthy to submetallic look and does not show Kammererite’s micaceous chlorite habit.
Kammererite vs. Similar Purple Minerals
| Mineral | Typical Look | Key Difference |
|---|---|---|
| Kammererite | Purple to reddish-purple platy crystals or foliated aggregates | Chromium-rich clinochlore; soft with chlorite cleavage |
| Lepidolite | Lilac mica flakes or granular masses | Lithium mica from pegmatites; often lighter and more pearly |
| Charoite | Swirled purple massive material | Distinct fibrous, swirling texture rather than platy crystals |
| Sugilite | Massive purple to violet material | Usually tougher-looking and lacks mica-like sheet cleavage |
| Purple Fluorite | Violet cubes, masses, or cleavable pieces | Cubic cleavage and glassier luster |
How to Check Kammererite Authenticity Before Buying
Authentic Kammererite is usually sold as a rare collector mineral rather than a mainstream tumbled stone. Look for natural purple platy crystals, chlorite-like cleavage, and a credible source locality such as chromite-associated deposits. Be cautious with vague listings that use only the color term “purple crystal” or offer large inexpensive polished pieces without mineral data.
Important Locality Clues for Kammererite
Kammererite is associated with chromium-rich geological settings, especially ultramafic rocks and chromite deposits. A reliable label may mention a mine, district, or country along with the mineral name. Locality alone does not prove identity, but it can help separate Kammererite from purple minerals that form in pegmatites, manganese deposits, or fluorite veins.
Kammererite in Jewelry and Display
Kammererite is better suited to protected display specimens than to jewelry that receives frequent contact. Its softness and cleavage make it vulnerable to scratching, flaking, and edge damage. If used in jewelry, it is most appropriate for protected pendants, earrings, or collector pieces worn sparingly.
What Is Kammererite?
Kammererite is a purple to pink, chromium-rich variety of clinochlore in the chlorite group. Its color can look dyed at first glance, since chlorite is usually green, flaky and plain. Kammererite instead shows a raspberry-purple that stands out strongly under bright display lighting.
Specimens usually appear lighter in the hand than in photographs. The habit is platy and micaceous, and the mineral tends to peel into thin sheets if handled carelessly. Crystals that look chunky in images are often stacks of thin plates, with small edges that reflect light like tiny mirrors. Set on pale green serpentine or whitish dolomite, the color contrast is the main appeal.
Kammererite is often confused with purple mica and with lepidolite. Lepidolite has a soft, greasy-looking mica appearance and is usually more lavender. Kammererite tends to range from hot pink to deep magenta-purple, and flashes from its cleavage surfaces can look silvery against the color.
Origin & History
Russia is where the name comes from. Kammererite got its first proper description in 1841 from the Bissersk area of the Ural Mountains, and it was named after Count Alexander von Kammerer, a Russian mining official who was tied into the region’s mineral work.
The label "Ural kammererite" is sometimes used as if it were a brand name. The older Ural material does have a recognizable character: crisp, platy crystals that split into thin plates, strong color, and a green serpentinite host rock typical of ultramafic geology. It is not a separate species. It is clinochlore, with chromium responsible for the color.
Where Is Kammererite Found?
Most collector-grade kammererite comes from chromium-bearing ultramafic terrains, especially the Urals in Russia and the Kop Krom area in Turkey. Smaller occurrences show up in Alpine serpentinites and a few classic North American localities.
Formation
Most of what you’re looking at is just raw chunks of ultramafic country rock, no surprises there. Kammererite shows up later, when chromium-bearing ultramafics like peridotite and dunite get hit with metamorphism and hydrothermal alteration, and serpentinization is doing a lot of the heavy lifting. The chromium gets mobilized enough to slip into the chlorite structure, and that’s the moment the purple starts to show.
Close inspection of the matrix on many specimens usually reveals an associated assemblage: serpentine, nearby chromite, sometimes dolomite or calcite, and other chlorites mixed in. The crystals tend to be platy or pseudohexagonal and sometimes form rosettes. They often sit in small seams and pockets, so many pieces have one well-formed face while the back is broken rock.
How to Identify Kammererite
Color: Color ranges from pinkish purple through lilac to deep magenta-purple, sometimes with greenish chlorite mixed in. The most eye-catching pieces show strong color zoning across platy crystals.
Luster: Luster is pearly to vitreous on cleavage faces, often with a bright micaceous flash when you tilt it.
Pick up the specimen and gently run a fingernail along an edge. If it wants to peel into thin plates, you’re in chlorite territory. The real test is the look of the cleavage faces under a single light source: kammererite gives sharp, silvery flashes off flat plates, not the sugary sparkle you get from quartz druse. And if a seller is calling it “purple mica,” ask what the matrix is. Serpentine with chromite specks is a very common pairing for kammererite.

Kammererite Health & Safety
Handling it is safe. But if you cut or grind it, you can kick up fine silicate dust, the kind that hangs in the air and settles as a gritty film on your bench. Don’t breathe the dust from any lapidary work.
Safety Tips
If you’re cutting it up or shaping it, don’t do it dry. Use water on the cut, keep the air moving with decent ventilation, and wear a real respirator, because that fine grit gets everywhere and you can taste it if you’re not careful. And if it’s just a display piece, it’s simpler: handle it, then wash your hands afterward if there’s dusty matrix on it (you’ll see the powder on your fingers).
Kammererite Value & Price
Price Range
Rough/Tumbled: $30 - $600 per specimen
Cut/Polished: $20 - $120 per carat
Value depends mainly on two factors: color saturation and crystal habit. Clean, sharp, platy crystals on a contrasting matrix, with crisp edges that catch slightly under a fingernail, sell for considerably more than dull, mixed chlorite seams that look muddy up close.
Durability
Fragile — Scratch resistance: Poor, Toughness: Poor
It’s stable in normal indoor conditions, but the platy crystals bruise and cleave easily if they rattle around.
How to Care for Kammererite
Use & Storage
Store it in a box or a display case where it won’t get bumped. Those thin plates chip fast when two specimens touch.
Cleaning
1) Use a soft brush to flick off loose grit. 2) Rinse briefly with lukewarm water and a drop of mild soap if needed. 3) Pat dry and let it air-dry fully before putting it back on the shelf.
Cleanse & Charge
For those who practice energetic cleansing, gentle methods are best: smoke, sound, or a brief pass over selenite. Burying platy kammererite in salt or soil is not advised, because the surface scratches easily.
Placement
A stable shelf away from high-traffic spots is best. Under a small spotlight, the cleavage flashes look great, but don’t aim for heat buildup.
Caution
Skip ultrasonic cleaners, steam cleaners, and any long soaks. And don’t just chuck it into a pouch with quartz or feldspar unless you’re fine with coming back to little scuffs and a chipped edge or two.
Works Well With
Uses, Symbolism and Collecting
Kammererite is valued mainly by mineral collectors, who prize saturated pink-to-magenta plates or rosettes set against a contrasting matrix such as pale green serpentine or whitish dolomite. Its softness rules out most jewelry and daily carry. Pocket pieces tend to lose edges and shed purple flakes through contact with keys and coins, so display in a padded case or on a shelf suits it best.
In crystal traditions, kammererite is associated with insight and quieter thinking, and with the Third Eye, Crown and sometimes Heart chakras. Practitioners link it with Scorpio and Capricorn and with the elements Earth and Water. It is typically used for meditation or as a desk stone. These associations are cultural beliefs, not proven effects, and the stone is no substitute for medical care. If cleansing is part of a practice, gentle methods such as smoke, sound or a brief rest on selenite avoid damaging the plates. Salt and soil can scratch the surface.
Common mistakes
- Identifying any purple micaceous mineral as Kammererite without checking geological context
- Assuming polished purple material is Kammererite when the natural crystal habit is hidden
- Confusing lepidolite’s lithium mica flakes with chromium-rich chlorite plates
- Using color saturation alone as proof of authenticity
- Buying high-priced specimens without clear photos, locality information, or seller expertise
- Testing suspected Kammererite with harsh scratch tests that can damage the specimen
