Healing crystal pouches or bags contain different types of crystals. There can be any number of crystals in the pouch, but mostly there are around 3 to 9. The crystals choose to cover all the chakras, combined according to your zodiac sign or put together for a specific use to benefit particular areas of the body.
A fertility pouch contains agate, bloodstone, carnelian and moonstone. A healing pouch comes with quartz, sodalite, sugilite and turquoise. A focus pouch should include dumortierite, fluorite, hematite and enhances concentration. Healing stones and crystal pouches put together with a specific purpose in mind contain crystals suited to that one purpose. You could get a combination of several stones that will help you in your lifestyle or profession, to address certain body parts or to focus on a particular chakra that needs special attention.
