Question: what is the difference between rutilated and tourmalinated quartz?
Answer: Rutile is a mineral, similar to tourmaline; both grow in long, needle-like crystals. Rutilated quartz is quartz with crystals of rutile, tourmalinated quartz is quartz with crystals of tourmaline. ... I've never seen tourmalinated quartz that was anything but black, though free tourmaline can be lots of different colors.
