Aventurine is a type of quartz. Mica and fuchsite particles in the quartz give the stone its green color and slight sparkle. Although green is the most common color, aventurine can also occur in reddish-orange tones (caused by hematite in the stone), blue tones, purples, pinks, and reds (caused by iron). These attractive colors make aventurine one of the more colorful of the semi-precious stones.
It may be found worldwide and is associated with good luck, prosperity, risk taking and emotional tranquility. Green aventurine is associated with the Heart Chakra and blue aventurine is associated with the Third Eye and Throat Chakra.
