Red agate is a variety of chalcedony with warm, translucent red-to-orange bands. In Chinese and Tibetan traditions, red agate is:
A protective stone. Red agate is believed to ward off evil and protect the wearer from harm — especially the harm caused by envy or jealousy.
A stone of vitality. Red agate's warm energy is associated with blood, life force, and physical stamina.
A grounding stone. Like the root chakra it connects to, red agate provides stability and emotional balance.
In Tibetan jewelry, red agate is often combined with turquoise — red representing earth and life, turquoise representing sky and spirit.
