Prehnite
A soft-yellow green colour (occasionally clear), Prehnite has a softening and calming energy that makes it one of the best crystals for quietening the mind and the emotions and is excellent for meditation, particularly through relaxing the vision and looking deeply into the crystal. It helps to unlock the unconscious mind and to dissipate anxiety and can help with hyper-activity, nightmares, phobias and fears. Useful as a diagnostic tool, it can show us the root causes of these.
Considered a good Feng Shui stone, Prehnite helps us to declutter and reorganise and helps us to be in harmony with nature and the elementals. Placed in a room, it can revitalise the energy.
