Sodalite brings order and calmness to the mind.  It encourages rational thought, objectivity, truth and intuition, along with verbalisation of feelings.  Sodalite brings emotional balance and calms panic attacks.  It enhances self-esteem, self-acceptance and self-trust.  Sodalite balances the metabolism, boosts the immune system and overcomes calcium deficiencies.  It combats radiation damage by soaking up electromagnetic smog.  Sodalite treats the throat, vocal cords, larynx and helps with hoarseness and digestive disorders.  It cools fevers, lowers blood pressure and stimulates the absorption of body fluids.  Sodalite can also help to prevent insomnia.
 
This piece of Sodalite is set in a Silver Moon and Stars shaped mount and measures 2.5cm approx in diameter. It is suspended from a 19 Inch 925 Silver chain. While not an official birthstone, sodalite has been associated with the month of November. It depends who you ask, however, as Leavy notes that zodiac-wise, it's also associated with Virgo and Libra (which are not November signs).
