Analcime vs Leucite
Analcime and Leucite are easy to confuse. Both sit near Mohs 5–5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Analcime and Leucite
- Both sit near Mohs 5–5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Analcime is Transparent to translucent, Leucite is translucent.
- They overlap in clear and gray, but Analcime also comes in pink and green and Leucite also comes in yellow.
- Well-formed crystals give it away: Analcime is Isometric, Leucite is tetragonal.
Analcime vs Leucite properties
| Property | Analcime | Leucite |
|---|---|---|

Which is more valuable?
Leucite is usually the more valuable of the two: a typical collector specimen runs about $35 against $20 for Analcime, and premium Leucite can reach $180 or more.
About Analcime
Analcime is a hydrated sodium aluminosilicate, NaAlSi2O6·H2O, and one of the few zeolites to crystallize in the isometric system rather than a lower-symmetry one. It typically forms trapezohedral crystals with twenty-four faces, giving specimens a distinctive rounded, many-sided appearance. Chemically it sits at the boundary between the zeolite and feldspathoid mineral groups.
About Leucite
Leucite is a potassium aluminum silicate feldspathoid that typically forms distinctive rounded, near-spherical trapezohedral crystals. It is white to gray and occurs as phenocrysts in potassium-rich volcanic rocks.
Analcime vs Leucite FAQ
Is Analcime the same as Leucite?
No. Analcime is a mineral while Leucite is a silicate mineral. Both sit near Mohs 5–5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Analcime from Leucite?
Both sit near Mohs 5–5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Hold a thin edge to the light: Analcime is Transparent to translucent, Leucite is translucent. They overlap in clear and gray, but Analcime also comes in pink and green and Leucite also comes in yellow.
Which is harder, Analcime or Leucite?
Leucite is harder: Mohs 5.75 against Mohs 5–5.5 for Analcime.
Which is more valuable, Analcime or Leucite?
Leucite is usually the more valuable of the two: a typical collector specimen runs about $35 against $20 for Analcime, and premium Leucite can reach $180 or more.
