Gemstone of the Month: Citrine

Citrine is the birthstone for the month of November. It is a quartz, and its chemical composition is silicon dioxide coloured with iron. It is not as flashy a gemstone as lapis lazuli, or malachite, or emerald, but it does have a quiet beauty all of its own.

It ranges in colour from light yellow to golden brown, and is only found in a transparent form. Natural citrine is rare, and most commercially available stones are actually heat-treated amethyst or smoky quartz; heat-treated stones nearly always have a reddish tinge to them, enabling the discerning to detect that the stones are not true citrines. Natural citrine is found mainly in Brazil, Madagascar and the United States, with minor deposits in Argentina, Myanmar, Namibia, Russia, Scotland and Spain.

Citrine makes lovely delicate unusual jewellery. See the Granary Knits store for these and other designs.
