Aquamarine helps overcome the fear of speaking, and is an excellent stone for teachers and presenters of all types. It relaxes speakers to a stage of consciousness in which they are fully aware of their own truths, wisdom and feelings, and able to articulate them with clarity and conviction. It also allows one to speak clearly and without anger in difficult situations. It is calming, soothing, and cleansing, and inspires truth, trust and letting go. In ancient lore, Aquamarine was believed to be the treasure of mermaids, and was used by sailors as a talisman of good luck, fearlessness and protection. It was also considered a stone of eternal youth and happiness.
