Interesting Facts: Blue quartz is simply macrocrystalline quartz that is blue. The term is used for - at least - three different types of quartz:
1 - quartz crystals that appear blue due to the so called Tyndall scattering effect caused by tiny inclusions;
2 - crystalline quartz that is blue due to more or less evenly distributed inclusions of blue minerals, like magnesio-riebeckite or tourmaline;
3 - a coarse grained, massive, macrocrystalline form of blue quartz not unlike aventurine quartz that is also colored by embedded blue minerals, like dumortierite;
