Amethyst Aura Tumblestone

Amethyst is one of the prettiest tumblestones to be found. It comes in a wide range of purple colours and is a variety of quartz (SiO2). The purple colours found naturally in Amethyst occur due to irradiation and the presence of impurities of iron and in some cases other transition metals. It is a very popular stone for use in all kinds of jewellry. Sold in single stones.
