Description

This is a truly eye-catching and unusually shaped cluster of intergrown quartz crystals from Brazil. What makes this specimen particularly special is the presence of blue tourmaline — also known as indicolite — included within the quartz, giving the crystals their distinctive bluish hue. In certain areas, the thick tourmaline needles are clearly visible inside the quartz, adding both visual intrigue and mineralogical value. A highly attractive and uncommon piece.
