Baryte vs Cryolite
Baryte and Cryolite 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 Cryolite
- 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 2.95–3.0 for Cryolite).
- Hold a thin edge to the light: Baryte is Transparent to opaque, Cryolite is Transparent to translucent.
- They overlap in clear, brown, and red, but Baryte also comes in yellow and blue.
- Well-formed crystals give it away: Baryte is Orthorhombic, Cryolite is Monoclinic.

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 Cryolite
Cryolite is a rare sodium aluminum fluoride mineral, Na3AlF6, historically significant as a flux in the industrial extraction of aluminum metal from bauxite ore. It is best known from a single massive deposit at Ivigtut, Greenland, which was, until its exhaustion, essentially the only commercially significant source on Earth. Its name comes from the Greek for "ice stone," reflecting its unusual property of becoming nearly invisible when submerged in water due to a refractive index close to that of water itself.
Baryte vs Cryolite FAQ
Is Baryte the same as Cryolite?
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 Cryolite?
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 2.95–3.0 for Cryolite). Hold a thin edge to the light: Baryte is Transparent to opaque, Cryolite is Transparent to translucent.
Which is harder, Baryte or Cryolite?
Baryte is harder: Mohs 3–3.5 against Mohs 2.5–3 for Cryolite.
Which is more valuable, Baryte or Cryolite?
Typical specimens of Baryte and Cryolite trade in a similar range, around $20.
