Blue lace agate is a beautiful, pale sky blue stone with concentric markings. It is a cryptocrystalline quartz stone. Agate is a banded chalcedony, the bands having been formed by rhythmic crystallization. Agates are found as nodules or geodes in siliceous volcanic rocks. This stone comes from southwest Africa.
Agate strengthens the power of the Sun in your astrological sign when you wear it. It helps you stay well-balanced. It sharpens the sight, illuminates the mind, and helps you speak.
Blue lace agate helps you develop and realize your inner peace. These stones affect the physical body, first at the densest levels, and then at the levels of some of the higher bodies as well.
