Avant Mining, located in Blue Springs, Arkansas, produces the finest quartz crystals in the world! Their clarity, mirror luster, striations, phantoms, variety, and large size give them this distinction. The mine was originally opened in 1944 by a US government funded company to produce oscillator quartz which was critical to the war effort. It lay abandoned after the war until 2014 when Avant Mining LLC purchased the property and reopened it. In late 2014 into 2015 Avant broke into two pockets which are the largest finds of high quality “rock crystal” quartz ever documented. Avant Mining has become the largest quartz crystal mining company in the world with over 11,400 acres of land and 20 crystal mines in Arkansas.
