Aventurine of Various Colours

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 yet it is still not readily recognized by the general public. The stone may be found worldwide.
