Striking, all natural amethyst pieces. Size, shape, and color may vary due to each piece's unique, natural formation. Colors include hints of light purple, dark purple, gray, and green. Some clusters include traces of rare and powerful sought-after minerals: Calcite, white crystal-like pieces or flower-petal like specks, symbolizes cleansing. Cacoxenite, golden earthy brown spots, encourages focus on positivity. Amethyst, the stone of healing and transformation, will create a peaceful and positive atmosphere in the home.
