Apatite vs Beryl
Apatite and Beryl are easy to confuse because both are minerals. Beryl is harder (Mohs 7.5–8) than Apatite (Mohs 5), so Beryl will scratch Apatite and not the other way round. A steel knife blade (Mohs 5.5) scratches it; a copper coin does not. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Apatite and Beryl
- Beryl is harder (Mohs 7.5–8) than Apatite (Mohs 5), so Beryl will scratch Apatite and not the other way round. A steel knife blade (Mohs 5.5) scratches it; a copper coin does not.
- They overlap in green, blue, yellow, and clear, but Apatite also comes in purple and brown and Beryl also comes in pink.

About Apatite
Apatite is the collective name for a group of calcium phosphate minerals, chiefly hydroxylapatite, fluorapatite, and chlorapatite, sharing the general formula Ca5(PO4)3(F,Cl,OH). It is the mineral that defines hardness 5 on the Mohs scale and forms the mineral component of bones and teeth in vertebrates. Gem-quality crystals range from pale green and blue to vivid neon blue-green varieties prized by collectors.
About Beryl
Beryl is a beryllium aluminum cyclosilicate, Be3Al2Si6O18, that crystallizes in the hexagonal system as six-sided prisms. Pure beryl is colorless, but trace elements produce a family of well-known gem varieties, including green emerald, blue-green aquamarine, and pink morganite. It typically forms in granite pegmatites, where slow cooling allows large, well-formed crystals to develop.
Apatite vs Beryl FAQ
Is Apatite the same as Beryl?
No. Both are minerals, but they are distinct species with different hardness, streak or luster. Beryl is harder (Mohs 7.5–8) than Apatite (Mohs 5), so Beryl will scratch Apatite and not the other way round. A steel knife blade (Mohs 5.5) scratches it; a copper coin does not.
How can you tell Apatite from Beryl?
Beryl is harder (Mohs 7.5–8) than Apatite (Mohs 5), so Beryl will scratch Apatite and not the other way round. A steel knife blade (Mohs 5.5) scratches it; a copper coin does not. They overlap in green, blue, yellow, and clear, but Apatite also comes in purple and brown and Beryl also comes in pink.
