Baryte vs Celestine
Baryte and Celestine 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 Celestine
- Both sit near Mohs 3–3.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Baryte is Transparent to opaque, Celestine is Transparent to translucent.
- They overlap in clear and blue, but Baryte also comes in yellow, brown, and red and Celestine also comes in gray, green, and orange.

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 Celestine
Celestine, also spelled celestite, is strontium sulfate, SrSO4, and the primary ore of strontium, crystallizing in the orthorhombic system. It is best known for growing in delicate pale blue, tabular crystals, a color that gave the mineral its name from the Latin caelestis, meaning heavenly. Celestine often forms alongside gypsum and calcite in sedimentary evaporite settings, distinguishing it from most other sulfate minerals of hydrothermal origin.
Baryte vs Celestine FAQ
Is Baryte the same as Celestine?
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 Celestine?
Both sit near Mohs 3–3.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Hold a thin edge to the light: Baryte is Transparent to opaque, Celestine is Transparent to translucent. They overlap in clear and blue, but Baryte also comes in yellow, brown, and red and Celestine also comes in gray, green, and orange.
Which is harder, Baryte or Celestine?
They are about equally hard, both near Mohs 3–3.5.
Which is more valuable, Baryte or Celestine?
