ETYMOLOGY: QUARTZ = comes from the Greek word "kristallos" meaning ice. And "Hard" in Slavic. TURMALINA = Turamali comes from the name given to the first Ceylon gems from. (Now Sri Lanka).

MINERALOGY: Quartz macrocrystalline, igneous, metamorphic, hydrothermal inclusions black tourmaline crystals of Quartz, these minerals as well as aqueous solutions and gas bubbles, can be enclosed by the growing crystal, sometimes inclusions occur in acicular crystals (thin needle-shaped crystals.)

READ MORE: There are three ways inclusions

⦁ The minerals that were formed before the quartz: Quartz crystals grow and "traps" And so the original form of the mineral is preserved, and
          These inclusions are called protogenéticas.

⦁ The minerals and quartz grew at the same time (these are called syngenetic inclusions). The form of the minerals listed often deviates from typical habits and ways that develop during growth unhindered

⦁ Minerals may include another by exsolution (separation of two different mineral ore on cooling). These inclusions are called Epigenetic.

MYTHOLOGY: There are many historical threads of different times and places on the quartz or rock crystal, for example according to the Celtic oral tradition, it was believed that quartz crystals were the fangs of dragons and therefore guards ancestral wisdom, the rhythms of nature and environmental wealth. Nero had to drink two glasses carve them famous moments in believing that the quartz favor with the gods. Pliny support the idea that the quartz was a frozen chemical and coming from the colder areas of the Alps.

The biggest fan of tourmaline was Tzu Hsi, who ruled China from 1860 to 1908. The Empress used the stone as a notch in pins watch chains, buttons or jackets Imperial Court and important people. The Empress now rests on a cushion tourmaline.

PROPERTIES: The quartz with tourmaline combines the energetic properties of quartz and the protective properties of tourmaline, releases tension, harmonize the disparate and opposing elements, becomes negative thoughts into positive thoughts, battles and helps solve personal conflicts.
