Aventurine is a variety of translucent quartz with abundant small plate- or flake-shaped inclusions. Light entering the quartz strikes these inclusions and reflects from them. This produces a sparkly appearance known as “aventurescence.” Aventurine is a gemstone variety of quartz characterized by its translucency and sparkly metallic inclusions. Glittery inclusions are typically composed of muscovite mica, which usually results in medium to dark green aventurine stones with a silvery green or blue sheen. The metallic inclusions give aventurine quartz a unique sparkling iridescent effect, known as ‘aventurescence’. The remarkable optical effect is owed to traces of muscovite mica, and often hematite or goethite. The most common colour of aventurine is green, but it may also be orange, brown, yellow, blue, or grey. Chrome-bearing fuchsite (a variety of muscovite mica) is the classic inclusion and gives a silvery green or blue sheen. Oranges and browns are attributed to hematite or goethite. Because aventurine is a rock, its physical properties vary: its specific gravity may lie between 2.64-2.69 and its hardness is somewhat lower than single-crystal quartz at around 6.5. When the inclusions are abundant and in a common orientation, their reflections can be eye-catching. This property, along with desirable colours, are what give aventurine its appeal as a gemstone. Aventurine is usually green but also occurs in orange, yellow, red, pink, brown, white, gray, and blue.
