Geological Formation of Amethyst Crystals

Amethyst forms when iron impurities within quartz crystals are exposed to natural radiation. The exposure to gamma rays from radioactive elements in surrounding rocks causes the iron to oxidize, resulting in the distinctive purple coloration. The intensity of the purple hue varies depending on the amount of radiation absorbed and the duration of exposure.

The Enigmatic Hues of Amethyst

The characteristic purple color of amethyst ranges from pale lavender to deep violet. The delicate lavender shades are often referred to as “rose de France” or “pale amethyst,” while the intense violet hues are known as “Siberian amethyst.” The depth of color is influenced by the concentration of iron impurities and the temperature at which the crystals form.
