What is the difference between natural and treated amethyst color?

Natural and treated amethyst colors differ primarily in their origin and appearance. Natural amethyst showcases hues that occur naturally due to geological processes, while treated amethyst involves human intervention to enhance or alter its color.

What is Amethyst?

Amethyst is a popular purple variety of quartz, prized for its vibrant color and clarity. Its hues range from light lavender to deep violet, making it a favored gemstone in jewelry. The color results from the presence of iron impurities and natural irradiation.

How is Natural Amethyst Color Formed?

Natural amethyst color is formed over millions of years through geological processes:

• Iron Impurities: The presence of iron in quartz contributes to the purple hue.
• Natural Irradiation: Exposure to natural radiation over time enhances the color intensity.
• Geological Conditions: Specific pressure and temperature conditions influence the final color.

Natural amethysts can vary in color intensity, often displaying zones of light and dark purple.

What is Treated Amethyst?

Treated amethyst involves human intervention to enhance or change its color. Common treatments include:

• Heat Treatment: Applied to lighten or deepen the color or to change it entirely (e.g., turning amethyst into citrine).
• Irradiation: Used to restore or intensify color after heat treatment.

These processes can make the color more uniform and vibrant, often increasing the gemstone’s market value.
