tanzanite often displays natural growth lines

Higher concentrations of copper typically result in more intense blue and green shades

Galena with Quartz - Specimen space tanzanite often displays natural growthMined from: Chenzhou mining district, Hunan Province, China Description: This specimen features a dense cluster of metallic galena crystals intergrown with milky to lightly translucent quartz points.
