Almost all citrine that is available on the market today is heat-treated amethyst. Natural citrine is pale yellow to pale orange, much lighter than the heat-treated material which is dark orange-brown to reddish-brown. All of the heat-treated material has a red tint, while natural citrine does not.
Citrine includes yellow to gold to orange brown shades of transparent quartz. Sunny and affordable, citrine can brighten almost any jewelry style, blending especially well with the yellow gleam of polished gold.
