Larsonite (aka Gary Green Jasper or McDermitt Green Jasper) is petrified bog wood that is found along the Nevada/Oregon border. A volcanic eruption took place between 11 and 14 million years ago covering the vegetation in ash, depriving it of oxygen and preventing decay - the perfect conditions to make a fossil! During the fossilization process, iron, aluminium, potassium, sodium and calcium in the ground water caused the signature green and blue colors.
