What Is My Zodiac Stone?
Sagittarius Birthstone & Crystals: Turquoise
♐ November 22 – December 21 · Turquoise
Sagittarius is the Jupiter-ruled fire sign of the archer: travelers, philosophers and optimists. Turquoise, worn by travelers for thousands of years and the December birthstone, is its modern stone. Topaz, the November birthstone, is the traditional one.
Blue stones dominate because of the sign's link to sky, distance and big ideas. Lapis lazuli is traditionally the stone of truth-seekers and students, sodalite is the modern pick for Sagittarians who blurt things out, and citrine keeps the natural optimism topped up during long winters.
