The stone that we call Carnelian today was called Sardius in the KJV of the Bible. Carnelian was worn by ancient warriors for courage and power. This is also an excellent stone for overcoming your fear of speaking in front of a crowd. Carnelian is also a great stone for enhancing your creativity and motivation. Physically, this stone has been used to treat arthritis, depression, back problems and kidney issues. Carnelian, being a symbol of passion and love, is a perfect stone to be used in the foundation in new Jerusalem.
