History & Lore :
Aventurine is a Silicon Dioxide and is a translucent to opaque variety of
microcystalline quartz. The color of the stone depends on the mineral impurities
contained within. Green Aventurine contains the mineral known as Fuchsite Mica,
whereas blue Aventurine contains the mineral Dumortierite.
Aventurine derives from the Italian word 'a ventura' meaning “by chance”. The derivation
of this name dates back to the 1700's-1800's when an Italian glass-maker accidentally
came across the discovery of this stone well unknowingly dropping copper filings
into some molten glass. It is believed that Aventurine is the only gemstone that
was man-made before its natural counterpart was discovered.
One of the most well-known Aventurine's is one carved by the famous Helmut Wolf
of the village Kirschweiler near Idar-Oberstain, Germany. He fashioned a fine green Indian Aventurine that stands 5.5 feet high and weighs 2.5 tons.
Aventurine is often referred to as the Gambler's Stone because it is known to bring
the wearer increased chance, opportunity, and good luck. It is also known to reduce
stress, relieve anxiety and calm one's emotions. Aventurine is known to enhance
creativity and develop both confidence and leadership qualities.
Physically Aventurine is known to treat disorders of the lungs and heart and can
help to increase muscle flexibility. An ancient Tibetan legend claims that the stone
can improve nearsightedness.
