Long necklace in sapphires and yellow gold. SAPPHIRE BLUE. Connected to the chakra of the throat, it stimulates intuition and the clarity of the mind. The Tables of the Law, delivered by God to Moses on Mount Sinai, were in sapphire, as was the seal of Solomon (the geometric structure of the sapphire is the star of David). Blue sapphire is the emblem of the divine world and immortality.
