Citrine is the “Merchant’s Stone,” because it is associated with success and prosperity. Older references are rare because it’s been confused with topaz until relatively recent times, but this use has been consistent. Citrine has been associated with the solar plexus chakra. It aids healing throughout the digestive system, and aids metabolism in general. For example, even though the thyroid gland is typically associated with the throat chakra because of its position, healers may use citrine to enhance its function.
