You can find a complete list of Stones & Crystals & their application by taking my correspondence course.
Stones can be used for divination, meditation, healing and magic. You should always keep your stones in a cloth bag large enough to fit your hand into. If you have an affinity for a certain stone or it’s color you can purchase a ring or a necklace setting of that color or type of stone. You can also place stones in medicine bags to carry in your pocket or to place around your neck. If you know someone who does jewelry or lapidary work, you can have the specific stone of your choice mounted in a ring or necklace setting. This is a brief list of what each color symbolizes
