The sacral chakra is located slightly below your navel and represented by the orange. It is linked to emotions and creativity. Citrine, Carnelian, and Orange Calcite can help magnify or balance the sacral chakra.

The solar plexus chakra in the upper abdomen represents will, mental capacity, and intellect. Its attributed color is yellow and when it is blocked, you probably lack confidence or feel fearful.
Healing stones that resonate with the solar plexus chakra are citrine, yellow sapphire, and amber.

The heart chakra at the middle of the chest represents love, compassion, and acceptance. Its primary color is green, the secondary is pink.
