Chrysanthemum Stone
Chrysanthemum Stone is sedimentary (porphyroblastic limestone/slate). In the hand, it rates 3 to 5 (matrix); sprays vary on the Mohs scale, and it runs black or dark gray matrix and white radiating flower bursts. Jet-dark stone blooming with white radiating crystal 'chrysanthemums', flat flower-burst sprays of pale blades frozen in black rock.
The geology.
Chrysanthemum Stone carries the formula (celestite/calcite/andalusite sprays in dark matrix). It belongs to the, system. Its listing category is sedimentary (porphyroblastic limestone/slate).
It sits at 3 to 5 (matrix); sprays vary on the Mohs scale. The surface reads dull matrix; pearly flower blades. Light behaviour is opaque. Specific gravity runs 2.6 to 3.0. The streak is white (flower minerals). It breaks with uneven; carves along matrix.
Jet-dark stone blooming with white radiating crystal 'chrysanthemums', flat flower-burst sprays of pale blades frozen in black rock.
It turns up mostly as polished plaques, carved and enhanced display stones or palm stones.
The origins.
Permian beds of Hunan and Hubei, China; related stones from Japan and Canada.
On value, the database notes: mid-range; large natural multi-flower plaques are prized.
Traditional associations.
In energy work traditions, associated with blossoming in adversity and right timing.
This is lore, and we label it as lore. The measurable facts are further up the page.
Spotting the real thing.
Jet-dark stone blooming with white radiating crystal 'chrysanthemums', flat flower-burst sprays of pale blades frozen in black rock.
Routinely enhanced: carving down the matrix to raise flowers is standard, fully painted fakes exist, inspect petals under magnification.
| Looks like | How to tell them apart |
|---|---|
| Painted/carved fakes | Many commercial pieces are enhanced, carved around natural flowers or fully painted; paint sits ON the surface and identical 'perfect' flowers repeat |
| Pyrite suns | Pyrite suns are metallic golden discs in slate |
| Scolecite sprays | Scolecite radiates in 3D within white matrix, not flat black stone |
At-home tests.
A loupe and a window seat settle most questions about chrysanthemum stone. No workshop required.
| Test | What you should see |
|---|---|
| Under a loupe | Flower blades show crystal structure under a loupe |
| By eye | Check whether 'petals' continue INTO the stone (carving exposes depth; paint doesn't) |
| Scratch check | Matrix often scratches with a knife |
Destructive tests belong to a gemologist, not a kitchen table. If a piece matters to you, pay for an appraisal before you take a file to it.
Care & handling.
At 3 to 5 (matrix); sprays vary on the Mohs scale this is a soft material. Keep it as a display piece, store it apart from harder stones, and skip daily-wear settings.
It breaks with uneven; carves along matrix, which is worth knowing before you set it or drop it.
Clean it by hand, dry it properly, and keep it away from ultrasonic cleaners and hot steam.
