Aventurine vs Goldstone
Aventurine and Goldstone are easy to confuse. Aventurine is harder (Mohs 6.5–7) than Goldstone (Mohs 5.5), so Aventurine will scratch Goldstone 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 Aventurine and Goldstone
- Aventurine is harder (Mohs 6.5–7) than Goldstone (Mohs 5.5), so Aventurine will scratch Goldstone 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: Aventurine leaves a white streak on unglazed porcelain, Goldstone leaves white to colorless.
- Hold a thin edge to the light: Aventurine is Translucent, Goldstone is opaque.
- They overlap in orange and brown, but Aventurine also comes in green, blue, and red and Goldstone also comes in yellow.
- Well-formed crystals give it away: Aventurine is Trigonal, Goldstone is amorphous.

About Aventurine
Aventurine is a variety of quartzite prized for aventurescence, a sparkly, glittery sheen caused by light reflecting off tiny platy mineral inclusions suspended within the rock. Green aventurine owes its color to included flakes of the chromium mica fuchsite, while orange to reddish varieties contain hematite or goethite instead. Though often sold alongside single minerals, it is technically a metamorphic rock made mostly of interlocking quartz grains.
About Goldstone
Goldstone is a manufactured glittering glass, usually coppery brown to orange, sold as beads, cabochons, and tumbled stones.
