History & Lore :
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 whilst 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 to 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 near-sightedness.

Aventurine is rated at 7 on Moh’s Scale of Hardness. It is translucent to opaque variety of microcrystalline quartz and contains small inclusions of minerals which reflects light and give the stone a sparkling effect known in the gem market as ‘aventurescence’. The color of the aventurescence depends on the mineral found within the stone. Peach Aventurine contains Hematite, Goethite, or Iron Micas which account for its peach to orangish-peach sparkle and color.
