The name of aventurine comes from the Italian phrase "a ventura" which means "by chance". According to the story, around 1700, in Murano, Italy, a type of glass was made by a glassmaker who accidentally dropped copper filings into the molten material. The resulting glass had an iridescent appearance and was called avventurino, giving its name to the stone, which had a similar appearance.
Avventurine was used in antiquity in various uses: in Ethiopia in the manufacture of weapons, in Tibet in the treatment of visual disorders, in the Inca civilisation as an amulet to obtain gold. In China it was considered a precious stone and was associated with the royal family and the goddess of mercy and compassion Guanyn Pusa. The Etruscans, on the other hand, associated it with the goddess of childbirth Thalna. Today, aventurine belongs to the class of semi-precious stones and is widely used in jewellery making.
The stone is endowed with powerful energetic powers. It helps in discharging the negative waves released by electronic and electrical appliances. It acts as a reinforcing agent in reducing stress and anxiety, positively stimulating the mind. It promotes concentration and decision-making. It has a beneficial effect on eye fatigue and headaches caused by eye fatigue. As an elixir, it relieves skin problems, soothes itching and accelerates healing. Balances blood pressure and stimulates metabolism.
It belongs to the Pyrite - Tectosilicate Minerals, it is a variety of quartz. Its crystal structure is triangular and has a translucent appearance. It is found mainly in green and more rarely in brown, red colour. The metallic iridescence that appears on its surface is created, in the green aventurine, by the scattered inclusions of fuchsite (green mica) and in the brown, red mica by the inclusions of iron mica. The optical effect, which gives the stone a radiant glow, is called aventurscence. Sources of aventurine are found in India, Brazil and Russia.
