Silver Leaf Jasper
Silver Leaf Jasper is silicate (jasper), SiO2 with iron oxide impurities. In the hand, it rates 6.5 to 7 on the Mohs scale, and it runs silver gray and white. Swirling leaf-vein patterns of silvery gray, white, and charcoal flowing through opaque jasper like brushed pewter. Commercial material primarily from Africa and India.
The geology.
Silver Leaf Jasper carries the formula SiO2 with iron oxide impurities. It belongs to the trigonal (cryptocrystalline) system. On paper it is silicate (jasper).
It sits at 6.5 to 7 on the Mohs scale. The surface reads vitreous on polish. Light behaviour is opaque. Specific gravity runs 2.58 to 2.91. The streak is white. It breaks with conchoidal fracture.

Expect to see it as tumbled, beads, spheres or cabochons.
The origins.
Commercial material primarily from Africa and India.
On value, the database notes: common and affordable.
Traditional associations.
In energy work traditions, associated with willpower and quiet protection during travel.
Recorded here because it is part of how this material is sold, not because it is a property of the material.

Not faked; mostly a bead-strand staple sold under loosely applied names.
| Looks like | How to tell them apart |
|---|---|
| Zebra jasper | Zebra shows bold straight stripes; silver leaf swirls in feathery veins |
| Picasso marble | Picasso marble scratches with a knife and fizzes with acid; silver leaf jasper scratches glass |
| Gray banded agate | Agate is translucent at edges; silver leaf jasper stays opaque |
At-home tests.
None of these need a lab. A 10x loupe, good daylight and a steady hand cover most of what a buyer needs to know about silver leaf jasper.
| Test | What you should see |
|---|---|
| Scratch check | Scratches glass (Mohs 6.5 to 7) |
| Acid check | No fizz with vinegar |
| Look for bubbles | Leafy swirl pattern rather than straight banding |
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 6.5 to 7 on the Mohs scale it handles careful wear but scratches against quartz and dust. Store it separately and take rings off before rough work.
It breaks with conchoidal fracture, 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.

What it gets confused with
Zebra jasper: Zebra shows bold straight stripes; silver leaf swirls in feathery veins. Picasso marble: Picasso marble scratches with a knife and fizzes with acid; silver leaf jasper scratches glass. Gray banded agate: Agate is translucent at edges; silver leaf jasper stays opaque.
What it is worth
Common and affordable.
Where buyers get caught
Not faked; mostly a bead-strand staple sold under loosely applied names.
One more thing
The name describes the look of silvery leaf veins, no actual silver is present, iron and clay minerals paint the gray tones.
