These rare double terminated quartz come from right here in Central NY. We live 1 hour from the mines and work closely with our independent mine sources to get the best crystals available. These are the Crystals that started it all in 2006. This quality and these sizes are the hardest to get in quantity. We hope you enjoy them as much as we do. 

We tend to sell out quickly of the larger sizes very fast. 

Gem Crystals (A, A+ or AA grade) over 1/2" (12.5mm) are very rare, even rarer at 1" in size with good clarity, 2"+ clear is rarely seen. Optical Clarity is rare especially single "floater" crystals like these with no contacts from the matrix.
