Coloured Gemstones: Quartz

Aaron Signature School Series

We love quartz! Um … prasiolite! Of the many varieties of quartz, this lesson is on “green quartz”, also known as vermarine. Colours range from very light translucent green (natural prasiolite) to darker green quartz (artificially treated). Rare in nature, almost all natural prasiolite has come from a small mine in Brazil. However, both Poland and Canada have become sources too. Just remember that heat treatment and ionizing radiation have been applied to almost all prasiolite gemstones!
