Yellow Sapphire is a type of Corundum, an aluminium oxide mineral containing trace amounts of iron that gives it its pale yellow to lemon yellow colour tones.
The frequency of yellow Sapphire connects to the sacral and solar plexus chakras, stimulating them so that one's creative thoughts can be manifested using focussed intent. The energy of yellow Sapphire helps to align one's personal will with divine will, so that one can bring into manifestation that which one desires in alignment with one's highest good.
It supports one when using one's personal power so that it is used in a positive, creative manner, bringing joy and happiness into one's life's experiences.
Yellow Sapphire helps with issues of prosperity and abundance, and supports one in keeping focussed to see one's thoughts put into action.
Via the solar plexus chakra yellow Sapphire can help with digestive issues and supports one's physical vitality.
