Kyanite is a stone that is tough to polish, which makes these earrings so unique and precious.  Their diamond shape is different as well.  The second stone hangs about an inch by a stainless steel chain.  As with all earrings, plastic backs are included to make sure they are snug and safe.  
  Kyanite is known to expand one's consciousness and connect your active mind with the sleeping...in other words, it allows you to have more participation in your dreamworld, often helping with mastering lucid dreaming.
