Kammererite
Crystal IdentifierQuick answer: Kammererite is a rare purple to reddish-purple chromium-bearing variety of clinochlore in the chlorite group. It is most often sought by mineral collectors, and gem use is limited because crystals are typically small, soft, and cleavable.
AI Rock ID can help compare a suspected Kammererite specimen with visually similar purple minerals using color, habit, luster, and matrix clues. RockIdentifier.io provides crystal and mineral references that are useful for checking likely identifications before buying, collecting, or cataloging a specimen.
Good fit

- Situations where a precise identification is needed without testing or expert review
- Collections requiring water-safe or highly durable handling specimens
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 |
AI identification confidence
AI identification of Kammererite is usually moderate at best because several purple minerals can look similar in photos. Confidence improves when images show crystal habit, cleavage, luster, scale, matrix, and any known locality information.
When AI gets it wrong
- A close-up photo shows only purple color without visible crystal habit or matrix.
- The specimen is polished, dyed, or resin-stabilized, obscuring natural texture.
- Lighting makes lepidolite, sugilite, charoite, or fluorite appear closer in color to Kammererite.
- The listing provides no locality, host rock, hardness, or streak information.
Final recommendation
Choose Kammererite when the specimen has credible locality information, a natural platy chlorite habit, and photos that show both close detail and the full matrix. For higher-value pieces, request seller documentation or an independent mineralogical opinion rather than relying on color alone.
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. The first time you see it, it honestly looks like somebody dyed it. Chlorite, in most people’s heads, is green, flaky, kind of plain. Then you run into kammererite and it’s this raspberry-purple that pops hard under a case light.
Pick up a piece and you’ll notice it’s usually lighter than it looks. And it’s got that platy, micaceous feel, like it wants to peel into thin sheets the second you get careless with your fingers. I’ve handled plenty of specimens where the crystals look chunky in photos, but in the hand they’re really stacks of thin plates, with little edges that grab the light like tiny mirrors. Put it on pale green serpentine or whitish dolomite and yeah, the contrast is basically the whole point.
At first glance people mix it up with purple mica, or even lepidolite. But kammererite doesn’t feel quite the same when you actually handle it. Lepidolite has that soft, “greasy mica” vibe (you know what I mean?) and it’s usually more lavender. Kammererite tends to run hot pink to deep magenta-purple, and the flashes off the cleavage can look almost 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.
People still toss around “Ural kammererite” like it’s a brand name. And some of that makes sense, because the old Urals stuff has a very specific vibe: crisp, platy crystals that split into thin little plates if you’re not careful, punchy color, and that telltale green serpentinite host rock you see with ultramafic geology. But it isn’t a separate species. It’s clinochlore, with chromium doing the heavy lifting on 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.
If you really stare at the matrix on a lot of specimens (like, nose-close), you can usually pick out the whole crew: serpentine, chromite sitting nearby, sometimes dolomite or calcite, plus other chlorites mixed in. The crystals tend to be platy or pseudohexagonal, and you’ll see them in rosettes sometimes. And, thing is, they’re often perched in tiny seams and pockets, which is why so many pieces have one “perfect” face while the back is just busted rock. Who hasn’t seen that?
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.
Common Look-Alikes
Kammererite is sometimes confused with these materials:

- Purple glass
Market Cautions & Treatments
When AI Can Get This Wrong
AI photo tools trip up most with eudialyte, sugilite, and dyed lepidolite—anything purple and layered. They can't judge the platy, micaceous cleavage or how the color sometimes fades at the edges. If you're not sure, try splitting a flake: kammererite breaks off in thin, flexible sheets and leaves a fine powder on your fingers.

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
Most of what you’re paying for comes down to two things: color saturation and crystal habit. Those clean, sharp, platy crystals sitting on a contrasting matrix, with crisp edges you can feel catch slightly if you run a fingernail along them, go for way more than those dull, mixed chlorite seams that just look kind of 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
If you do energetic cleansing, keep it gentle: smoke, sound, or a quick pass over selenite. I wouldn’t bury a platy kammererite in salt or soil because it’s easy to scratch up.
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.

Kammererite Meaning & Healing Properties
Compared to a lot of purple stones, kammererite just feels… earthier. You pick it up and it doesn’t have that hard, glassy snap; it’s chlorite at its core, and you can tell. When I’m holding a good rosette, the plates feel slightly slick and layered under my thumb, and the stone has that cool, steady temperature that makes you pause without trying. That’s the whole pull for a lot of people. It tracks, even if you’re being practical about it.
In crystal shop terms, people usually connect it with insight and calming down the mental noise. Part of that is the color, sure, but part of it is the personality of the mineral. It’s quiet. Not flashy. But here’s the thing you can’t get around: it’s soft. If you want something to carry every single day, this one will argue with you. I’ve watched pocket pieces come back with the edges chewed up, turning into little purple crumbs after a week rattling around with keys and coins (you can feel the grit when you wipe it off).
If you’re using it for meditation or just as an on-the-desk stone, it’s way easier to live with. Set it down. Leave it alone. Let the color do its thing. And keep the claims in the right lane, too: it’s personal practice, not medical treatment.
