Description Aventurine is green in color but is related to quartz minerals like citrine and amethyst. What is commonly referred to as red aventurine is actually a variety of the mineral feldspar called sunstone. Aventurine and sunstone's similar glittery appearance is caused by microscopic particles of other minerals. Particles of mica form green aventurine and particles of hematite form sunstone. History After an 18th century Italian glassmaker accidentally created a kind of glass that looked remarkably similar to a glistening green variety of quartz, aventurine was named for the Italian phrase a ventura meaning "by chance."
