One-of-a-kind natural amethyst. You will receive a piece similar to those shown. Size: 5 to 6 inches (sizes vary) Amethyst is a violet variety of quartz, a silicon dioxide mineral. It forms in volcanic environments where silica-rich fluids fill cavities and crystallize over time. Its purple color is caused by iron impurities combined with natural geological irradiation during formation. These specimens typically show pointed crystal terminations with a translucent to transparent structure, often mounted on a metal stand to display the natural crystal growth. Each item is unique in shape, color, and pattern. Higher-grade pieces are selected first. Photos represent overall quality and appearance.
