Baryte vs Cinnabar
Baryte and Cinnabar are easy to confuse because both are minerals. Baryte is harder (Mohs 3–3.5) than Cinnabar (Mohs 2–2.5), so Baryte will scratch Cinnabar and not the other way round. A fingernail (Mohs 2.5) scratches it easily. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Baryte and Cinnabar
- Baryte is harder (Mohs 3–3.5) than Cinnabar (Mohs 2–2.5), so Baryte will scratch Cinnabar and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
- Streak color differs: Baryte leaves a white streak on unglazed porcelain, Cinnabar leaves scarlet red.
- Cinnabar feels noticeably heavier for its size (specific gravity 8.0–8.2 versus 4.3–4.6 for Baryte).
- They overlap in brown and red, but Baryte also comes in clear, yellow, and blue and Cinnabar also comes in gray.
- Well-formed crystals give it away: Baryte is Orthorhombic, Cinnabar is Trigonal.

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 Cinnabar
Cinnabar is mercury sulfide, HgS, the principal ore mineral of mercury and one of the most historically significant toxic minerals in human history. It forms a brilliant red to brownish-red mineral typically deposited by low-temperature hydrothermal fluids near volcanic activity and hot springs, often associated with recent or geologically young volcanic terrains. Cinnabar has been mined for millennia both for its metal content and, historically and dangerously, as a pigment source.
Baryte vs Cinnabar FAQ
Is Baryte the same as Cinnabar?
No. Both are minerals, but they are distinct species with different hardness, streak or luster. Baryte is harder (Mohs 3–3.5) than Cinnabar (Mohs 2–2.5), so Baryte will scratch Cinnabar and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
How can you tell Baryte from Cinnabar?
Baryte is harder (Mohs 3–3.5) than Cinnabar (Mohs 2–2.5), so Baryte will scratch Cinnabar and not the other way round. A fingernail (Mohs 2.5) scratches it easily. Streak color differs: Baryte leaves a white streak on unglazed porcelain, Cinnabar leaves scarlet red. Cinnabar feels noticeably heavier for its size (specific gravity 8.0–8.2 versus 4.3–4.6 for Baryte).
