Cherry Quartz vs Sunstone
Cherry Quartz and Sunstone are easy to confuse. Sunstone is harder (Mohs 6.5) than Cherry Quartz (Mohs 5.5), so Sunstone will scratch Cherry Quartz and not the other way round. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Cherry Quartz and Sunstone
- Sunstone is harder (Mohs 6.5) than Cherry Quartz (Mohs 5.5), so Sunstone will scratch Cherry Quartz and not the other way round. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will.
- Streak color differs: Cherry Quartz leaves a white to colorless streak on unglazed porcelain, Sunstone leaves white.
- Hold a thin edge to the light: Cherry Quartz is translucent, Sunstone is transparent.
- They overlap in pink, red, and clear, but Sunstone also comes in orange and yellow.
- Well-formed crystals give it away: Cherry Quartz is amorphous, Sunstone is triclinic.

About Cherry Quartz
Cherry Quartz is a trade label for pink to red manufactured glass, often sold as beads, cabochons, or decorative stones.
About Sunstone
Sunstone is a gem feldspar known for aventurescence, a glittering metallic shimmer caused by tiny reflective platelets of copper, hematite, or goethite. It ranges from golden to orange and red and is cut as a gemstone.
