Beryl vs Quartz
Beryl and Quartz are easy to confuse. Both sit near Mohs 7.5–8, 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 Beryl and Quartz
- Both sit near Mohs 7.5–8, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- They overlap in pink, yellow, and clear, but Beryl also comes in green and blue and Quartz also comes in purple, black, gray, and brown.
- Well-formed crystals give it away: Beryl is Hexagonal, Quartz is Trigonal.
Beryl vs Quartz properties
| Property | Beryl | Quartz |
|---|---|---|
| Type | Minerals | Quartz Family |
| Mohs hardness | 7.5–8 | 7 |
| Luster | Vitreous | Vitreous, greasy on fracture surfaces |
| Streak | White | White |
| Transparency | Transparent to translucent | Transparent to translucent |
| Specific gravity | 2.63–2.92 | 2.65 |
| Crystal system | Hexagonal | Trigonal |
| Common colors | Green (emerald), Blue (aquamarine), Pink (morganite), Yellow (heliodor), Colorless (goshenite) | Colorless, White, Purple (amethyst), Yellow (citrine), Pink (rose), Brown/black (smoky) |
| Rarity | common | common |
| Typical specimen value | $2–$150+ | $5–$250+ |
Which is more valuable?
Quartz is usually the more valuable of the two: a typical collector specimen runs about $35 against $20 for Beryl, and premium Quartz can reach $250 or more.
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.
About Quartz
Quartz is silicon dioxide, SiO2, one of the most abundant minerals in Earth's continental crust, crystallizing in the trigonal division of the hexagonal crystal system with a hardness of 7 that makes it a standard reference point on the Mohs scale. Its six-sided prismatic crystals, often terminated by pyramidal points, are among the most recognizable crystal shapes in mineralogy. Quartz occurs in nearly every rock type and geologic setting, from granite pegmatites to sedimentary sandstones to hydrothermal veins.
Beryl vs Quartz FAQ
Is Beryl the same as Quartz?
No. Beryl is a mineral while Quartz is a quartz family. Both sit near Mohs 7.5–8, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Beryl from Quartz?
Both sit near Mohs 7.5–8, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. They overlap in pink, yellow, and clear, but Beryl also comes in green and blue and Quartz also comes in purple, black, gray, and brown. Well-formed crystals give it away: Beryl is Hexagonal, Quartz is Trigonal.
Which is harder, Beryl or Quartz?
Beryl is harder: Mohs 7.5–8 against Mohs 7 for Quartz.
Which is more valuable, Beryl or Quartz?
Quartz is usually the more valuable of the two: a typical collector specimen runs about $35 against $20 for Beryl, and premium Quartz can reach $250 or more.
