Amethyst. The February-born shall find Sincerity and peace of mind, Freedom from passion and from care, If they an amethyst will wear. â Gregorian birthstone poem.

Amethyst was likewise consistently designated as the February birthstone in the old Roman, Italian, Polish, Russian, Hebrew, Arabic and the old Indian (Ayurvedic) calendar. Before the gemstone became the birthstone of February in these ancient calendars, amethyst was the main zodiac stone for Pisces and Aquarius, both zodiac signs falling partly on the month of February.
