Natural Citrine seems to have been popularized by those in the metaphysical community, leading to sky-high prices and unscrupulous suppliers, heating amethyst/smoky quartz AND labeling it as “Natural Citrine”. But what many people don’t seem to realise is that ALL Citrine starts out as Amethyst: the mined, as opposed to heat treated, crystals have simply been heated by geological processes (i.e. American Mineralogist: 55: 246-263.

As Ethan has already mentioned, one of the key ways to spot a heat treated Citrine is that it will have a white base and a bright golden to brown termination, whereas the natural crystal will have a relatively even but much duller colour all over.
