We present spectroscopic analyses that characterize the distribution and abundance of hydroxyl-bearing impurities within a single quartz crystal grown in hydrothermal fluid. We focus on a gemmy quartz crystal collected in ...

Quartz crystals have been studied since ancient times by scientists and natural philosophers attempting to unlock the mysteries behind their aesthetic appearance and cryptic morphological properties. Previous studies ...

Gemmy hydrothermal quartz crystals typically exhibit each of their six prism and six rhombohedral crystal faces. However, discerning which of the crystal faces were actively growing at any given time during construction ...
