Rutile (or rutilated) quartz is clear or smoky quartz with inclusions of rutile crystals. Rutile is the mineral name for natural crystals of titanium dioxide. While most varieties of transparent quartz are valued most when they show no inclusions, rutilated quartz is valued specifically for the lovely patterns formed by the delicate golden needles of rutile inside it. We've just purchased an interesting lot from India of this fascinating gemstone. Each piece is entirely unique.
