Platinum (Native)
Platinum (Native) is native element (metal), Pt (with Fe, Ir, Os alloying). In the hand, it rates 4 to 4.5 on the Mohs scale, and it runs steel gray and silver-white. Steel-gray metal heavier than gold-colored anything, never tarnishes, dents rather than breaks, and some nuggets tug weakly on a magnet (iron alloying).
The geology.
Platinum (Native) carries the formula Pt (with Fe, Ir, Os alloying). It belongs to the isometric system. Its listing category is native element (metal).
It sits at 4 to 4.5 on the Mohs scale. The surface reads metallic, untarnishing. Light behaviour is opaque. Specific gravity runs 14 to 19. The streak is steel gray, shining. It breaks with hackly fracture; malleable.
Steel-gray metal heavier than gold-colored anything, never tarnishes, dents rather than breaks, and some nuggets tug weakly on a magnet (iron alloying).
It turns up mostly as placer grains and nuggets, rare crystals or sperrylite-bearing ore.
The origins.
Placers and layered intrusions: Urals (Russia, historic nuggets), Bushveld (South Africa), Stillwater (Montana, USA), Colombia.
On value, the database notes: precious metal pricing; natural crystals are museum rarities.
Traditional associations.
In energy work traditions, platinum is linked with clarity, neutrality, and amplifying subtle energies.
This is lore, and we label it as lore. The measurable facts are further up the page.
Spotting the real thing.
Steel-gray metal heavier than gold-colored anything, never tarnishes, dents rather than breaks, and some nuggets tug weakly on a magnet (iron alloying).
'Platinum nuggets' online are often silver-plated lead or steel, density and magnet behavior expose them.
| Looks like | How to tell them apart |
|---|---|
| Silver | Silver tarnishes black and is lighter; platinum stays bright and outweighs it |
| Steel shot/shavings | Steel is strongly magnetic and rusts; platinum at most responds weakly and never corrodes |
| Galena | Galena is brittle, cleaves into cubes, and blackens fingers |
At-home tests.
A loupe and a window seat settle most questions about platinum (native). No workshop required.
| Test | What you should see |
|---|---|
| By eye | Extreme density (SG 14+) |
| By eye | No tarnish ever |
| By eye | Malleable, dents under a pin |
| Magnet check | Sometimes weakly magnetic (iron-bearing nuggets) |
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 4 to 4.5 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 hackly fracture; malleable, 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.

The physical record
The formula on record is Pt (with Fe, Ir, Os alloying). Crystal system: Isometric. Specific gravity: 14 to 19. Streak: Steel gray, shining. Cleavage and fracture: Hackly fracture; malleable.
How it reaches the market
Placers and layered intrusions: Urals (Russia, historic nuggets), Bushveld (South Africa), Stillwater (Montana, USA), Colombia.
What it gets confused with
Silver: Silver tarnishes black and is lighter; platinum stays bright and outweighs it. Steel shot/shavings: Steel is strongly magnetic and rusts; platinum at most responds weakly and never corrodes. Galena: Galena is brittle, cleaves into cubes, and blackens fingers.
What it is worth
Precious metal pricing; natural crystals are museum rarities.
Where buyers get caught
'Platinum nuggets' online are often silver-plated lead or steel, density and magnet behavior expose them.
One more thing
Spanish colonists discarded 'platina', little silver, as worthless sand; the nuisance metal now outprices the silver they kept.
An education-first guide.
We do not stock platinum (native). Writing it up regardless is the point of a reference library.
