Dalmatian Stone
peralkaline igneous rock: albite + quartz + arfvedsonite
Not a jasper and not tourmaline-spotted: a peralkaline microgranite from Chihuahua whose black flecks are arfvedsonite, an amphibole. The entire crystal trade has been repeating the wrong identification for forty years, which makes it a useful teaching specimen. People carry it for grounding, calm and boundaries. Tradition attaches it to the element earth, the root, sacral chakra, Mercury.

What it is
Not a jasper and not tourmaline-spotted: a peralkaline microgranite from Chihuahua whose black flecks are arfvedsonite, an amphibole. The entire crystal trade has been repeating the wrong identification for forty years, which makes it a useful teaching specimen. Cheap, cheerful, and universally mislabelled.
What it is confused with
leopardskin-jasper, snowflake-obsidian, granite, white-howlite
Off-white to cream body scattered with rounded, irregular black spots of varying size, plus occasional rust-orange staining. Under 10x the white matrix is visibly granular and crystalline, interlocking feldspar and quartz grains, not a smooth chalcedony body, which is how you know it is an igneous rock and not a jasper. The black spots are stubby prismatic amphibole (arfvedsonite), sometimes showing a faint cleavage sheen, and they are NOT black tourmaline despite what the label says.
How to tell
Look at the white matrix under magnification: granular interlocking crystals mean dalmatian stone (an igneous rock), smooth waxy body means jasper. The black spots will not scratch glass as readily as tourmaline would, arfvedsonite is around 5, 6 and shows cleavage.
What it means for you
The Moon is at 1° Scorpio today. Dalmatian Stone is a rock (aggregate), 6-7 on the Mohs scale, and it is the stone traditionally carried when the problem is proximity rather than intensity.

Dalmatian Stone for every sign
Aries
Forty years is a long time to repeat a first guess.
The black spots are arfvedsonite, an amphibole, and the trade has called them tourmaline for forty years without checking. The white body around them is a peralkaline microgranite from Chihuahua, granular under a lens where a jasper would look waxy. Forty years is a long time to repeat a first guess.
Taurus
Cheap, cheerful, universally mislabelled.
The black spots are arfvedsonite, an amphibole, and the trade has been calling them tourmaline for forty years. The white around them is a peralkaline microgranite from Chihuahua, granular under a lens where a jasper would look smooth and waxy. Cheap, cheerful, universally mislabelled.
Gemini
Forty years of wrong tags and nobody changed the sign.
Every label in the trade says the black spots are tourmaline. They are arfvedsonite, an amphibole that will not scratch glass, sitting in a peralkaline microgranite from Chihuahua. Forty years of wrong tags and nobody has changed the sign.
Cancer
It has carried somebody else's name for forty years.
Shop labels say the black spots are tourmaline. They are arfvedsonite, an amphibole soft enough to pit under a nail file, set in a Chihuahuan microgranite. The stone has carried somebody else's name for forty years without complaining once.
Leo
Two wrong names, one cheap rock, forty years running.
The black spots are arfvedsonite, an amphibole, and the trade has been calling them tourmaline for about forty years. The white body is a peralkaline microgranite from Chihuahua, visibly granular under a lens, which rules out jasper as well. Two wrong names on one cheap rock.
Virgo
Two wrong identifications printed on one label.
The black spots are arfvedsonite, an amphibole, and the trade has been calling them black tourmaline for about forty years. Under a lens the white matrix shows interlocking feldspar and quartz grains, which makes it a Chihuahuan microgranite rather than a jasper. Two wrong identifications on one label.
Libra
Nobody wanted the argument, so the wrong name stayed.
The black spots are arfvedsonite, an amphibole, and not black tourmaline, whatever the label says. The white body is interlocking feldspar and quartz, which makes this a peralkaline microgranite rather than a jasper. Forty years of the trade repeating a wrong identification because nobody wanted the argument.
Scorpio
Forty years of the trade repeating one wrong answer.
The black spots are arfvedsonite, an amphibole, whatever the label says about tourmaline. Under a lens the white body is granular interlocking feldspar and quartz, which makes the whole thing a peralkaline microgranite from Chihuahua. Forty years of the trade repeating one wrong answer.
Sagittarius
The black spots are arfvedsonite, not tourmaline, whatever the label says.
The black spots are arfvedsonite, an amphibole, and not black tourmaline whatever the label says. The white around them is granular interlocking feldspar and quartz, which makes the whole thing a microgranite from Chihuahua. Forty years of the trade repeating one error.
Capricorn
Universally mislabelled, and annoying in a way you quietly enjoy.
The black spots are arfvedsonite, an amphibole, and the white body is granite. There is no jasper here and no tourmaline either, which the trade has been getting wrong for forty years. Cheap, cheerful, universally mislabelled, and annoying in a way you will quietly enjoy.
Aquarius
The trade has repeated the wrong identification for forty years.
The black spots are arfvedsonite, an amphibole, and the pale body is interlocking feldspar and quartz, which makes this an igneous rock rather than any kind of jasper. The trade has repeated the wrong identification for forty years. Aquarius has been correcting it for about as long.
Pisces
Forty years of mislabelling has changed nothing about the rock.
The black spots are arfvedsonite, an amphibole, and the pale body is interlocking feldspar and quartz grains you can see without a lens. It is a microgranite from Chihuahua, not a jasper. Forty years of mislabelling has changed nothing about the rock.

What tradition says
In crystal lore, dalmatian stone is associated with playfulness, loyalty and breaking out of over-seriousness, attributions that derive entirely from the dog it is named after rather than any older tradition.
Care
- Water is fine. Dry it afterwards.
- Durable enough for handling, though the amphibole spots are softer and can pit. Warm water only.
