Selenite with Lithium is a new find for me, and I love the combination of the two stones.  These pieces are clear like windows. 
 
Selenite with Lithium will clear negative energies and relieve stress/anxiety.  I feel that they go a step further and will like a window, allow you to look at the causes of the stress/anxiety and also where the negative energies are coming from (people/situations) to see the root issues clearly.  This gives you the opportunity to resolve situations and to rid yourself of stress, anxiety, and negative energies.  The pieces are calming and will make your soul feel lighter.
 
I feel that this would make a great piece to use as a healing tool.  It has a pointed tip which can be used to concentrate and direct the energy.
