Aventurine vs Prasiolite
Aventurine and Prasiolite are easy to confuse. Both sit near Mohs 6.5–7, 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 Aventurine and Prasiolite
- Both sit near Mohs 6.5–7, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Aventurine is Translucent, Prasiolite is transparent.
- They overlap in green, but Aventurine also comes in blue, orange, brown, and red and Prasiolite also comes in yellow.
- Well-formed crystals give it away: Aventurine is Trigonal, Prasiolite is trigonal.

Which is more valuable?
Prasiolite is usually the more valuable of the two: a typical collector specimen runs about $60 against $20 for Aventurine, and premium Prasiolite can reach $300 or more.
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 Prasiolite
Prasiolite is a pale leek-green variety of quartz, transparent and glassy with the same hardness and durability as other quartz. Most prasiolite on the market is heat-treated amethyst, since naturally green quartz is uncommon.
