Blue Scheelite or Lapis Lace Onyx is a grounding stone that helps calm, relax and center. The stone also assists with shamanic and astral journeying by expanding one's psychic visions and capabilities. It is generally believed that meditating with the stone helps encourage mindfulness and compassion.
I only have one of these pendants, and it is truly stunning. Size is 1" from top of bail to bottom of pendant.
