Geminis are the first air sign of the zodiac. Symbolized by the twins and the relationship between polarities, they possess a dual nature and expansive mind. Adept communicators, creatives, and intellects, they are benefited by gemstones that ground earth energies, impart water influence, and assist in harmonizing mind and heart. Given their affinity with the throat chakra, necklaces are a natural placement for gemstone therapy, along with anything worn in pairs, such as earrings or a set of bracelets.
