Wearing crystals and gems can benefit your general health and wellbeing, as well as offering spiritual protection and energetic stability. Crystals can have a balancing effect on your whole subtle energy system. Clear quartz is a fabulous all-rounder healing crystal that can be inspired with whatever intention you choose, so it is an excellent choice if you are starting to wear crystals for their healing benefits.
Emotional balance. Individual crystals can help you feel calmer and at ease through their energetic influences and grounding effects. Others can help balance your heart chakra to be more open to giving and receiving love, or expressing joy.
Mental Clarity. Crystals such as Smokey Quartz or Black Tourmaline can aid mental clarity by grounding excess mental energy, clearing the mind. Other great stones for calming the mind are Blue Lace Agate, Fluorite, Blue Calcite and Clear Quartz. 
Enhance intuition and spiritual abilities. Some crystals are reputed to open up psychic and spiritual abilities, as well as connect us to higher levels of conscious awareness. Clear, purple and indigo blue stones are great for this purpose, such as Amethyst, Iolite, Azurite, Lapis lazuli, Moonstone and Labradorite.
