Speaking of amethyst, did you know that amethyst has been "...thought to control evil thoughts, quicken intelligence, make a shrewd man in business, preserve soldiers from battle wounds, aid the warrior to victory, help the hunter in search of his game, protect the wearer from contagious diseases, and put demons to flight if the figure of a bear is inscribed on the jewel. Amethyst was known as a gem that would bring forth the highest, purest aspirations of human kind. " credit: JewelsForMe
Sodalite, the marbled blue and white stone that accents the blue spiral earrings, also has some positive attributes associated with it. From TrinityLondon: Sodalite is "...believed by some to instill confidence and courage. It is also thought to be a soothing stone which can increase sensitivity to others."
Who knew that stones could have such positive attributes, and, some even believe, actual poweres? Whether they increase intelligence or confidence, semiprecious gems certainly are beautiful.
