Gemini's astrological gem is the AGATE.

In traditional medicine, the agate is used for stomach upsets. It may also have the power to foster emotional harmony. It is said that if you place an agate on the solar plexus, it can't change your emotions, but it will help to change your level of acceptance about your feelings. For instance, if you are feeling depressed and sad, the agate will let you know that this will pass and help you make it to another, better day.
