Baryte vs Fluorite
Baryte and Fluorite are easy to confuse because both are minerals. Both sit near Mohs 3–3.5, 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 Baryte and Fluorite
- Both sit near Mohs 3–3.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Baryte feels noticeably heavier for its size (specific gravity 4.3–4.6 versus 3.2 for Fluorite).
- Hold a thin edge to the light: Baryte is Transparent to opaque, Fluorite is transparent.
- They overlap in clear, yellow, and blue, but Baryte also comes in brown and red and Fluorite also comes in purple, green, and pink.
- Well-formed crystals give it away: Baryte is Orthorhombic, Fluorite is cubic.
Baryte vs Fluorite properties
| Property | Baryte | Fluorite |
|---|---|---|
| Type | Minerals | Minerals |
| Mohs hardness | 3–3.5 | 4 |
| Luster | Vitreous, pearly on cleavage | vitreous |
| Streak | White | White |
| Transparency | Transparent to opaque | transparent |
| Specific gravity | 4.3–4.6 | 3.2 |
| Crystal system | Orthorhombic | cubic |

Which is more valuable?
Fluorite is usually the more valuable of the two: a typical collector specimen runs about $25 against $20 for Baryte, and premium Fluorite can reach $200 or more.
About Baryte
Baryte, also spelled barite, is barium sulfate, BaSO4, best known among minerals for its unusually high density despite being non-metallic in appearance. It commonly forms tabular crystals and rosette clusters in hydrothermal veins and sedimentary rock cavities, and its name comes from the Greek barys, meaning heavy. Baryte serves as the primary industrial ore of barium and is used worldwide as a weighting agent in drilling fluids.
About Fluorite
Fluorite is a colorful mineral that often exhibits multiple colors in a single specimen. It's the defining mineral for 4 on the Mohs hardness scale.
Baryte vs Fluorite FAQ
Is Baryte the same as Fluorite?
No. Both are minerals, but they are distinct species with different hardness, streak or luster. Both sit near Mohs 3–3.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Baryte from Fluorite?
Both sit near Mohs 3–3.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Baryte feels noticeably heavier for its size (specific gravity 4.3–4.6 versus 3.2 for Fluorite). Hold a thin edge to the light: Baryte is Transparent to opaque, Fluorite is transparent.
Which is harder, Baryte or Fluorite?
Fluorite is harder: Mohs 4 against Mohs 3–3.5 for Baryte.
Which is more valuable, Baryte or Fluorite?
Fluorite is usually the more valuable of the two: a typical collector specimen runs about $25 against $20 for Baryte, and premium Fluorite can reach $200 or more.
