Aventurine Round Cabochon

This round aventurine cabochon has an attractive light green color; its durability makes it a great option for all types of jewelry—bracelets and rings as well as more protected pendants and earrings. Use it as a budget-friendly alternative to jade, or for its own subtle, distinctive characteristics. Aventurine is a quartzite gemstone composed of interlocking grains of quartz and mica or iron crystals. It is most commonly green, and can range from mostly translucent to opaque. Because the mica and iron crystals are reflective, they create a sparkle effect from beneath the gemstone surface, giving the gemstone the characteristic phenomenon that carries its name: aventurescence. Its name is derived from the Italian “a ventura” meaning “by chance,” owing to the accidental nature of its discovery.
