MantraOnNet.com: Crystal Shapes
Single terminated wands
These have a single point at one end and a rough or rounded edge at the other. They are used widely in healing, cleansing and meditation and as jewellery.
Chunks
Chunks are crystals without notable facets. They can be good for enriching a rooms atmosphere, for holding during meditation or simply carrying in your pocket.
Clusters
Clusters consist of a group of small crystals that have naturally grown joined together. Clusters can be excellent for enriching a living environment or workplace. Depending upon their properties they can cleanse, invigorate or calm an atmosphere.
Cut crystals
Cut crystals are crystals that have been cut and polished into shapes such as pyramids, wands or spheres, which can make them very attractive. If they are well-cut the energy of the stone can be maintained and sometimes amplified.
Tumblestones
Tumblestones are small stones, rocks or crystals that have been tumbled over each other many times with increasingly finer abrasive until the sides become smooth and shiny. Many people like to carry a tumblestone around in their pocket to keep the energy of the stone with them throughout the day.
