Lapis Lazuli
Lapis Lazuli is metamorphic rock (lazurite + calcite + pyrite). In the hand, it rates 5 to 5.5 on the Mohs scale, and it runs royal ultramarine blue and brassy pyrite flecks. Deep ultramarine blue flecked with brassy gold pyrite glitter, the gold-on-blue combination is the fingerprint. The classic: Sar-e-Sang, Badakhshan (Afghanistan), mined 6,000+ years; also Chile, Russia.
The geology.
It is classified as metamorphic rock (lazurite + calcite + pyrite).
It sits at 5 to 5.5 on the Mohs scale. The surface reads dull to vitreous. Light behavior is opaque. Specific gravity runs 2.7 to 2.9. The streak is light blue. It breaks with uneven fracture.
Deep ultramarine blue flecked with brassy gold pyrite glitter, the gold-on-blue combination is the fingerprint.
You will most often meet it as tumbled, beads, cabochons, carvings or spheres.
The origins.
The classic: Sar-e-Sang, Badakhshan (Afghanistan), mined 6,000+ years; also Chile, Russia.
On value, the database notes: mid-range; intense even blue with fine pyrite is prized.
The sourcing score.
We cannot name the mine, the cooperative, or the people who dug it. Most lapis on the market reaches sellers through several intermediaries, and the paperwork stops well short of the pit.
We have found no published environmental oversight covering the main deposits, and no chain of custody that would let us verify any if it existed.
Lapis is widely imitated with dyed howlite and dyed jasper, and genuine material is often dye-enhanced without that being disclosed at the point of sale.
Value runs mid-range, and fine even blue with tight pyrite carries a premium. Grading is subjective and undisclosed treatment moves the price, so a quoted grade means little on its own.
We have no verified information about who cuts, carves, and polishes the material, or what they are paid for it.
Traditional associations.
In energy work traditions, associated with truth and self-knowledge.
People buy on this language, so it belongs on the page. It belongs under the facts, though, not over them.
Spotting the real thing.
Deep ultramarine blue flecked with brassy gold pyrite glitter, the gold-on-blue combination is the fingerprint.
Widely faked (dyed howlite/jasper, 'reconstituted' blocks) and often dye-enhanced even when genuine, pyrite flecks and acetone tests help.
| Looks like | How to tell them apart |
|---|---|
| Sodalite | Sodalite is grayer blue with white veins and almost never carries pyrite |
| Dyed howlite ('lapis') | Soft, dye lifts with acetone, no real pyrite |
| Dyed jasper ('Swiss lapis') | Uniform blue with no pyrite and dye in fractures |
At-home tests.
You can run every one of these at a kitchen table. Good light matters more than gear when you are looking at lapis lazuli.
| Test | What you should see |
|---|---|
| By eye | Look for brassy pyrite specks |
| Solvent swab | Acetone swab stays clean on natural stone |
| Scratch check | Knife scratches it with effort (Mohs 5 to 5.5) |
Anything that scratches, burns or dissolves the piece is a lab job. Get it appraised rather than testing it apart.
Care & handling.
At 5 to 5.5 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 uneven fracture, which is worth knowing before you set it or drop it.
Warm water and a soft cloth clean almost everything. Ultrasonic tanks, steamers and household cleaners are where pieces get ruined.

The physical record
Specific gravity: 2.7 to 2.9. Streak: Light blue. Cleavage and fracture: Uneven fracture.
How it reaches the market
The classic: Sar-e-Sang, Badakhshan (Afghanistan), mined 6,000+ years; also Chile, Russia.
What it gets confused with
Sodalite: Sodalite is grayer blue with white veins and almost never carries pyrite. Dyed howlite ('lapis'): Soft, dye lifts with acetone, no real pyrite. Dyed jasper ('Swiss lapis'): Uniform blue with no pyrite and dye in fractures.
What it is worth
Mid-range; intense even blue with fine pyrite is prized.
Where buyers get caught
Widely faked (dyed howlite/jasper, 'reconstituted' blocks) and often dye-enhanced even when genuine, pyrite flecks and acetone tests help.
One more thing
Ground lapis was Renaissance ultramarine, a pigment once costlier than gold, reserved for painting Mary's robes.
