Rutilated Quartz is one of the few gemstones desirable because of its inclusions. This gives it a special allure and desirability as a unique gemstone type. Rutilated Quartz exists mainly in colorless, transparent Quartz, although a brown, smoky Rutilated Quartz also exists but is less common. Other color varieties of Quartz are rarely if ever encountered in rutilated form.
Rutilated Quartz is an affordable gemstone, and may be cut into large gemstones. It may also be cut into cabochons and beads, and may be carved into large ornamental spheres.
Rutile QuartzRutilated Quartz is natural and not enhanced.The chief source of Rutilated Quartz is Brazil, and another important source is India. It is encountered elsewhere but is uncommon from other locations.The unique formation of Rutilated Quartz easily distinguishes it from all other gemstones, except for Rutilated Topaz. Rutilated Topaz is harder, has more brilliance, and its inclusions are different than Rutilated Quartz (its inclusions are Limonite rather than Rutile). Scapolite is a common mineral, and its typical habit is in opaque and uninteresting forms. However, several unique localities provide gemmy transparent forms of this mineral, which make a rare and pretty gem. However, despite its lovely colors, Scapolite has been limited from becoming a more mainstream gemstone due to its relatively low hardness.
