Real vs fake Lapis Lazuli at a glance
| Genuine Lapis Lazuli | Imitation | |
|---|---|---|
| Pyrite | Real metallic gold flecks | Painted on or absent |
| Calcite | White patches | Too-uniform blue |
| Dye | None | Rubs off with acetone |
How to tell real Lapis Lazuli
- Real lapis carries natural gold pyrite flecks (metallic, not painted) and patches of white calcite; painted-on "gold" is a fake.
- Dye rubs off on an acetone-dampened cotton bud, and the blue is often too uniform.
- Reconstituted lapis looks too perfect and even; natural lapis varies across the stone.

Genuine lapis has natural pyrite (real metallic gold flecks) and some white calcite, with uneven blue. Dyed howlite/jasper has painted or absent pyrite, dye that rubs off with acetone, and a suspiciously uniform colour.
What is Lapis Lazuli worth?
Real Lapis Lazuli and its imitations differ a lot in value — see the value guide. Imitations (glass, dyed or reconstituted material) are worth a small fraction of the genuine stone.
