Jewelry attracts energy first, it can act as armor protecting you from negative energies, while it also attracts the good. People wore crowns since the beginning of the time surrounding their higher chakras with gems and gold to activate and protect. Necklaces do work for your throat and heart chakras. You can also activate jewelry by attaching meaning to a piece, or at to make it a talisman. Gold vibrates the highest, then silver, the other metals follow. Gems and crystals each have properties of their own.
