Appearance, Uses and History
Tourmaline included Quartz is pretty much exclusively used as a decorative stone, whether it is cut for jewellery or kept as a mineral specimen.
Essentially, this material consists of Tourmaline growing inside, outside, or through Quartz crystals.
The most prized material tends to be growths of Tourmaline ‘needles’ growing inside Quartz crystals, or well defined Tourmaline crystals growing on a Quartz matrix.
The most common material tends to be black Tourmaline, otherwise known as Schorl. Schorl in Tourmaline is relatively inexpensive, except in the highest qualities.
Tourmaline included Quartz is often used for beads or cut into cabochons, although it is rarely faceted.
It is important to make a distinction between ‘tourmaline in quartz’ and ‘rutile in quartz’. Rutile is a form of Titanium with golden needles, whereas Tourmaline is typically black or another colour.
However, a visual examination of internal inclusions will not be conclusive to guarantee the inclusions are Tourmaline – there are other needle like inclusions which occur in a range of colours, including black.
A significant amount of Tourmaline included Quartz comes from Brazil, with other locales known in Germany, Switzerland, India, Sri Lanka, Madagascar, Pakistan and the USA.
The chemical formula would, therefore, be SiO2 with (Na or CA)1(Mg,Li,Al and/or Fe2+)3Al6(BO3)3Si6O18(OH)4

Hazards and Warnings
Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.
When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
It is worth pointing out that ‘tourmalanated’ and ‘tourmalinated’ are portmanteaus – combined words. They are unlikely to translate into other languages well, if at all.
Therefore the translations below only cover ‘tourmaline in quartz’ and ‘tourmaline included quartz’.
