5" Double-Terminated, Tessin Habit Smoky Quartz Crystal - Nigeria

This is a natural, double-terminated smoky quartz crystal that was collected from Taraba, Nigeria. It has beautiful smoky coloration throughout the crystal and terminations along both ends. There are small, fibrous black inclusions within the crystal that attribute to the smoky coloration. The tapered shape of the crystal is classified as "Tessin Habit" which is defined as having a smaller cross section the closer you get to the termination. This habit often occurs in conditions of high pressure and temperature.
