Morganite vs Quartz
Morganite and Quartz are easy to confuse. Both sit near Mohs 7.75, 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 Morganite and Quartz
- Both sit near Mohs 7.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Morganite is transparent, Quartz is Transparent to translucent.
- They overlap in pink and purple, but Quartz also comes in clear, yellow, black, gray, and brown.
- Well-formed crystals give it away: Morganite is hexagonal, Quartz is Trigonal.
Morganite vs Quartz properties
| Property | Morganite | Quartz |
|---|---|---|
| Type | Silicate Minerals | Quartz Family |
| Mohs hardness | 7.75 | 7 |
| Luster | vitreous | Vitreous, greasy on fracture surfaces |
| Streak | White | White |
| Transparency | transparent | Transparent to translucent |
| Specific gravity | 2.8 | 2.65 |
| Crystal system | hexagonal | Trigonal |
| Common colors | Pink, Peach, Salmon, Pale violet | Colorless, White, Purple (amethyst), Yellow (citrine), Pink (rose), Brown/black (smoky) |
| Rarity | rare | common |

Which is more valuable?
Morganite is usually the more valuable of the two: a typical collector specimen runs about $250 against $35 for Quartz, and premium Morganite can reach $2000 or more.
About Morganite
Morganite is the pink to peach variety of beryl, colored by traces of manganese. A durable and softly toned gemstone, it forms in pegmatites as transparent tabular crystals and is cut into faceted gems.
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.
Morganite vs Quartz FAQ
Is Morganite the same as Quartz?
No. Morganite is a silicate mineral while Quartz is a quartz family. Both sit near Mohs 7.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Morganite from Quartz?
Both sit near Mohs 7.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Hold a thin edge to the light: Morganite is transparent, Quartz is Transparent to translucent. They overlap in pink and purple, but Quartz also comes in clear, yellow, black, gray, and brown.
Which is harder, Morganite or Quartz?
Morganite is harder: Mohs 7.75 against Mohs 7 for Quartz.
Which is more valuable, Morganite or Quartz?
Morganite is usually the more valuable of the two: a typical collector specimen runs about $250 against $35 for Quartz, and premium Morganite can reach $2000 or more.
