Rutilated Quartz is Quartz stone with Rutile enclosures. Rutile is a mineral made up mostly of Titanium Dioxide. It’s very high on the refractive index and disperses more than almost any other mineral which means when it appears in other minerals it almost always appears in long, thin shots of color. Rutile is the Latin word for red and got it’s name because some Rutiles are deep red in color. Rutiles can also appear in brown, grey and gold tones.
Quartz is the second most common mineral in the Earth’s continental crust. It is mainly composed of Silica or Silica based minerals. Although Quartz is known by a variety of names, the most important distinction between types of Quartz is that of macro-crystalline, individual crystals visible to the unaided eye, and micro-crystalline, where aggregates of crystals are only visible under high magnification. There are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral impurities or heat treatments.
