Amethyst Crystal with a Deep Purple Colour
Beautifully translucent, deep purple-coloured amethyst crystals from Namibia.
These crystals are smaller-sized tumbled stones.
Being translucent, the natural colour of amethyst is best appreciated when the stone is held up to the light. Some colour zoning is present, which is a typical characteristic of amethyst.
Amethyst's deep purple colour comes from iron impurities within its crystal structure, which are altered by natural radiation over time. The varying shades of purple are caused by the concentration of iron and the specific conditions under which the amethyst formed.
