Here’s a more detailed breakdown:

1. Citrine in Nature: Natural Citrine is quite rare and typically has a pale yellow or light golden color, which is often not as vibrant as what is seen in most Citrine jewelry.
2. Heating Process: To create a more vivid, rich yellow or golden hue, Amethyst crystals (which are purple in color) are exposed to high heat (around 450°C – 750°C). This process alters the iron content in the Amethyst, transforming its color from purple to yellow or gold, resulting in a bright, sunny appearance.
3. Energy and Healing: While the heating process enhances the color, heat-treated Citrine retains the same healing properties as natural Citrine, such as boosting energy, abundance, and mental clarity. The process does not negatively affect its metaphysical properties.
4. Ethics and Transparency: Heat treatment of Citrine is widely accepted in the gemstone industry, and reputable sellers often disclose this treatment to ensure transparency with customers.

So, when you see Citrine that’s heat-treated, it’s essentially Amethyst that has undergone a transformation to achieve a warmer, golden color, while maintaining its energetic and metaphysical qualities.
