 QUARTZ WITH TOURMALINE



INFORMATIONS


Tourmaline is known as the rainbow gemstone because it occurs in all colours of the spectrum and is in fact a group of 14 different mineral varieties. The composition of Tourmaline is sufficiently complex that mineralogist John Ruskin in 1891 described it as "more like a medieval doctor's prescription than the making of a respectable mineral." Tourmaline is the Brazil more spectacular gemstone and the more sough after mineral by collectors. Of course Tourmaline in quartz is also a dream. Tourmalinated quartz is usually included by black elongated crystals. Its recognition as tourmaline is often difficult because many others black minerals are found in the same quartz deposits and with similar shapes. For that reason black tourmaline in quartz are usually called graphite by local dealers and miners. More appreciated and much more rare and expensive is the quartz included with gem colored tourmalines. Green is rare, but pink or plichrome is super rare.
All pegmatite mines, between the thousands presents in the state of Minas Gerais, Brazil, can virtually produce quartz crystals with tourmalines included.
