This crystal is known as a Dow crystal, two of the faces on the point have 7 edges, as a result : if one holds the crystal point away and slightly down one can see a three dimensional pyramid in the point. This Crystal wieghs in at 1.2 Kg. It is a very powerful healing tool, especially for a crystal therapist like myself.
