Editing Quartz (section)

===Ametrine===
[[Ametrine]], as its name suggests, is commonly believed to be a combination of citrine and amethyst in the same crystal; however, this may not be technically correct. Like amethyst, the yellow quartz component of ametrine is colored by iron oxide inclusions. Some, but not all, sources define citrine solely as quartz with its color originating from aluminum-based color centers.<ref name=":0" /><ref>{{Cite web |title=Ametrine |url=https://www.mindat.org/min-7606.html |access-date=2025-01-10 |website=www.mindat.org}}</ref> Other sources do not make this distinction.<ref name=":2">{{Cite web |title=Quartz (var. ametrine) {{!}} Smithsonian National Museum of Natural History |url=https://naturalhistory.si.edu/explore/collections/geogallery/10002876 |access-date=2025-01-10 |website=naturalhistory.si.edu |language=en}}</ref> In the former case, the yellow quartz in ametrine is not considered true citrine. Regardless, most ametrine on the market is in fact partially heat- or radiation-treated amethyst.<ref name=":2" />
