Birthstones / February
February: Amethyst
Traditional: Amethyst · Purple, pale lilac to deep violet · Mohs 7
What it is
Purple quartz, colored by iron and irradiation in the earth. Large clean crystals are common (Brazil, Uruguay, Zambia), so it is one of the most affordable gems in big sizes. Most amethyst is untreated; some is heated to lighten it, and heated amethyst becomes citrine.
In the glossary: Amethyst.
Care
Soap and water; keep out of prolonged strong sun, which fades the color over years.
Before you buy
Deep, even purple with red flashes (the 'Siberian' color) is the top grade; pale 'Rose de France' is cheaper and pretty. Lab-grown amethyst exists and should be labelled.
