Shattuckite is my go-to stone to use for ghost hunts or in haunted buildings or areas.  It will protect you and keep entities from attaching to you while still allowing you to channel any spirits that are present (if you wish to do this).  
 
It is also said to heal emotional wounds which leads to improved resilience, wisdom, and emotional balance especially during difficult times.  The calming blue stone reduces aggression, impulsivity, and hypercriticism.  
 
Shattuckite allows you to express who you are and your truth in a compassionate and honest way.  There is a gentleness and sensitivity about this stone.  It promotes patience, tolerance, and acceptance.
