Stunning, 5" Amethyst Cluster - Las Vigas, Mexico
This is a stunning, amethyst crystal cluster from Las Vigas, Mexico. The entire piece measures 5x3.6" and there are dozens of beautiful crystals with nice terminations protruding at multiple angles.
Amethyst is a purple variety of quartz (SiO2) which gets its violet color from irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions.
