Aventurine is a form of quartz that can have a glimmering, almost metallic shimmer. The word aventurine comes from the Italian "a ventura" which means by chance. This name was inspired by aventurine's resemblance to a type of Italian glass that was discovered by accident in the 18th century.
Aventurine's most common color is green, but it also appears in shades of orange, brown, yellow, blue and gray. Sometimes aventurine contains inclusions of other minerals that give the gemstone a glittery shine. Aventurine with mica inclusions has a silvery sheen, while aventurine with hematite has a reddish or greyish sparkle. Aventurine is mostly shaped into cabochons or stones for use in rings, earrings, aventurine necklaces and bracelets.
Gem-quality aventurine is found in India, Brazil, China, Russia and Tanzania.
According to ancient Tibetan legend, aventurine was used to improve nearsightedness and increase creativity.
Today, many believe aventurine is a stone of luck or chance. It is also said the gemstone can help calm a troubled mind and bring about inner peace.
Aventurine is on the softer side (6.5 on the Mohs scale), so scratches and sharp blows should be avoided. To clean, simply wipe your aventurine jewelry with a moist cloth. Aventurine gemstones can fade, so it's best to store your aventurine rings, earrings, necklaces and aventurine bracelets out of direct sunlight.
