Not everyone will react the same to the same crystal. Even if you’re looking for the same purpose, you will be drawn to certain crystals for different reasons and purposes. Take it all in with your eyes and see what captures your attention and what you are captivated to.
Hold the crystal in your dominant hand, lift it up, sense the energy. Does it feel good? Does it strengthen your energy? If it does, it resonates with you. If you don’t feel anything, try it in your non dominant hand, if there is a weakening sensation when you try put it in your palm – the crystal would not be a good fit.
Something I like to encourage is go visit a few crystal stores in person. Walk around the store, observe and see if any specific crystal calls out to you.
