Aragonite vs Baryte
Aragonite and Baryte are easy to confuse because both are minerals. Both sit near Mohs 3.5–4, 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 Aragonite and Baryte
- Both sit near Mohs 3.5–4, 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 2.93–2.95 for Aragonite).
- Hold a thin edge to the light: Aragonite is Transparent to translucent, Baryte is Transparent to opaque.
- They overlap in clear, yellow, and blue, but Aragonite also comes in gray and pink and Baryte also comes in brown and red.

About Aragonite
Aragonite is calcium carbonate, CaCO3, crystallizing in the orthorhombic system as a metastable polymorph of the more common mineral calcite. It readily forms in low-temperature settings such as caves, hot springs, and the shells of many marine organisms, and it slowly converts to calcite over geologic time. Twinned crystal clusters resembling six-rayed stars are among its most recognizable forms.
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.
Aragonite vs Baryte FAQ
Is Aragonite the same as Baryte?
No. Both are minerals, but they are distinct species with different hardness, streak or luster. Both sit near Mohs 3.5–4, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Aragonite from Baryte?
Both sit near Mohs 3.5–4, 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 2.93–2.95 for Aragonite). Hold a thin edge to the light: Aragonite is Transparent to translucent, Baryte is Transparent to opaque.
Which is harder, Aragonite or Baryte?
Aragonite is harder: Mohs 3.5–4 against Mohs 3–3.5 for Baryte.
Which is more valuable, Aragonite or Baryte?
Typical specimens of Aragonite and Baryte trade in a similar range, around $20.
