Many crystals, especially those of the quartz family, naturally form in points. Points are excellent for focusing energy, attention or expression.
Great crystals to consider are members of the quartz family. Look for a natural quartz point. Any of the following are great: clear quartz point, citrine quartz point, smoky quartz point, rose quartz point, rutilated quart point, Lemurian quartz point or even Aura quartz points. A large clear quartz point is a great generator crystal to clear and magnify the energy of all of your other crystals.
