637gms 15.5 x 6 x 4.5cm Lightning quartz are just a story to themselves. And only found in the Serra do Esphinhaco mountains of brazil. In this region, orographic thunderstorms happen often in this region and the lightning strikes the side of the mountain. These spectacular specimens are formed when the lightning hits the mountains and travels through the earth striking the quartz. Evidence is shown by the zig zag pattern left on the crystal. With the rapid heating and cooling of the quartz and extremely high temperatures, it allows for inclusions of beta quartz and cristobalite to be formed in the crystal. This can only be obtained with temperatures above 573 degrees Celsius and 1,715 degrees Celsius respectively. This make Lightning struck quartz an extremely high vibrational, rare, highly prized and sought-after specimen.
