Citrine
SiO2
Citrine is yellow to orange quartz, naturally rare and mostly from Brazil, Zambia and the Congo. Almost all commercial 'citrine' geodes and points are heat-treated amethyst, recognisable by the orange-brown colour concentrated at the tips and a white base. Natural citrine is pale lemon and evenly coloured.
