Stars represent hope, positivity and happiness.
The waning moon presents a time for rest and reflection. It encourages you to look inward and find peace. 
 
Pyrite is a stone of abundance, confidence, and protection. It blocks negative energy, and brings strength. It is connected to the sun and is all around a very powerful influence.
 
The pyrite in combination with the waning position of the moon will give you both power and strength, and serenity and introspection, with the star's positive light.
