Gemini, First Half: May 20-June 4

Orange sapphire has long been associated with communication, specifically the telling of truths. As a soul stone, it can help early-half Geminis achieve the mastery of communication that is their karmic due. Sapphires are the hardest of gems after diamonds. In India of old, the orange sapphire was prized beyond any other; it was called padparadscha, the Sanskrit word for lotus blossom. The Chaldeans associated this stone with this sign after observing the orange tint of the planet Mercury, the ruler of Gemini.

 Moss agate, quartz with a plantlike pattern caused by metallic crystalline grains, is the power stone for first-half Geminis and represents the dualism of this sign of the Twins. The ancients actually thought the dark green markings inside the stone were fossilized moss. They used moss agate for water divining, so it was especially sacred to farmers. It is associated with the metal-rich planet Mercury and makes a great grounding stone for members of this air sign, who need to keep their feet on the ground.

 The heart stone for early Geminis is staurolite, named from the Greek word staurus, which translates to “cross.” Staurolite forms a natural crucifix because of the way the iron molecules in the stone line up. Bright red is one of the colors associated with Geminis, and staurolite most commonly appears in this vibrant color, causing it to be mistaken for garnet. This stone can help Geminis align with their true purpose, so they will benefit from keeping it at their bedsides or on their desks.

 Gemini, Second Half: June 5-June 20

Cat’s-eye, the lovely golden yellow gem, is the special soul stone for late-born Geminis. The ancient Greeks, who called this crystal cymophane, meaning “waving light,” believed this stone guarded against danger to the soul and the body. The iridescent surface of the stone causes it to appear in different colors; the shade depends on the angle from which the cat’s-eye is being seen. This mutable stone reflects back to Geminis their changeable nature and helps them to acknowledge their quicksilver personalities and to grow from that deep recognition. Geminis, wear a cat’s-eye ring and see your soul reflected back at you.

 Late Geminis can count on the garnet known as Transvaal jade, or grossular, for their power. People most often think of garnets as red stones of great clarity, but this specimen is opaque and a beautiful bright green. Under certain light, it appears as a blazing yellow color. This ability to change color symbolizes the dual nature of the June-born. Originating many millions of years ago in the deep core of the earth, Transvaal jade contains many metals in its makeup, a fact that also corresponds to the Gemini nature of having so many different qualities and talents. Wearing this garnet can awaken hidden talents in Geminis and bring them to the fore.

Geode, which usually comes in two split halves, is the ideal heart stone for later-born Geminis, but they must have both halves to help integrate the two parts of their nature and make for a complete, whole person. Geodes are formed from old volcanic bubbles and are usually solid agate outside with a center of gorgeous amethyst, opal, or rock crystal. If you are a Gemini, I recommend keeping one of the geode halves at home on your altar or in a special spot where you can see it every day and the other half at your place of work, to reflect and connect the two parts of your nature.
