The chalcedon is a quartz stone and as it confers calm and serenity, it is ideal for those who have strenuous activities or do work that involve danger. It favors those who undertake a journey, especially if it is long. The emerald is great to develop intuition and has a lot to do with wisdom and knowledge. This is why it is considered the stone of intelligence. Is very suitable for predicting future events and to exercise memory. Turquoise is the symbol of peace and quiet, and it is said to calm the violent outbursts and hatred, and one that brings a peaceful death after a long life. If a woman who wants to become a mother bears this stone, it encourages their children to be intelligent and healthy.
