Heat Treated & Natural Citrine

Posted by Emma Dearnaley on

Citrine is a crystal that is well known to many people, it's sunny energy and popularity as a crystal that attracts prosperity and abundance makes it a firm favourite among many. What you might not know however, is that about 95% of the Citrine on the market is actually heat treated Amethyst, or "fake" Citrine. To create heat treated Citine (also called burnt Amethyst), an Amethyst crystal is baked at temperatures of around 800-900 degrees Farenheit, this changes the colour to deepening shades of orange, depending on how long it is "cooked" for.

It can be quite difficult at first to know what you're buying, as most shops don't label their crystals as heat treated Amethyst, and even now, many crystal authors still have photos of burnt Amethyst crystals labelled as Citrine. Once you learn a few key points however, you will easily be able to tell them apart.

1. The Main Colour

Natural Citrine can vary from a very pale yellow shade, almost green in colour, such as Congo Citrine (also called Kundalini Citrine), to a stronger deep, often smokey yellow such as the long crystals from Zambia. Natural Citrine is hardly ever a deep burnt yellow-orange colour, this is almost always burnt Amethyst, although there are exceptions.

2. The Base Colour

Natural Citrine crystals are the same colour all the way through for the most part, though there may be slight colour variations in the crystal. Heat Treated Citrine will often have opaque white in it, usually at the base, which is a tell-tale sign of a heated crystal due to it's original Amethyst form.

Natural Citrine tends to grow in single crystals or small clusters of a few crystals, and never in a geode form. You will often see geodes of varying sizes that look suspiciously like orange Amethyst, this is exactly what they are.




Here are some images of Citrine being sold by retailers that are actually ALL heat treated Amethyst:

Notice how the bright orange/yellow colour is not even, there is the white base of the crystal, and that the formations look exactly the same as an Amethyst crystal? 

Here are some pictures of Natural Citrine from different regions:

Notice how the colour of these Citrine crystals is much lighter and more of a greeny shade? The first and last pictures are Citrine from the Congo, the second picture is Citrine from Zambia, two of the most famous natural Citrine localities. 

All of the Citrine we sell is natural, and mostly from the Congo and Zambia. Many crystal healers say it doesn't matter whether your Citrine is natural or heat treated Amethyst, but personally I believe that both Citrine and Amethyst are amazing crystals in their natural forms, and I would rather have them in the colour nature created them. Hopefully this article has helped to show the difference between the two crystals, if it has, please share it to help spread the knowledge!

  • Such a clear article, it’s so obvious when you see the examples side by side! Both are gorgeous naturally, I personally feel it’s such a shame heat treating the amethyst.
