Citrine is a protective stone with the association of luck through the planet Jupiter. It can help sooth negative energies from previous experiences and keeps those negative energies away. Use this to increase mental clarity, the auric field, gentle sexual stimultion, and bring balance to the body systems like the nerves, endocrine, and digestion.
This one in particular is an iridescent, sunshine lemon yellow.
As a spirit quartz, it amplifies the citrine properties over and over again based on all its tiny pints of shimmering crystals.
