Smoky Quartz Crystal. Mined By: Amanda Adkins From Prospectors. Amanda Adkins from Prospectors mined this beauty in Mount Antero, Colorado during one of her tapings of the show. I was able to hand pick this specimen from her collection at "The Tucson Gem & Mineral Show". This beautiful smoky quartz crystal has natural form and definition, which makes it perfect for master healing on all levels.
