Yes, all crystals can store their natural energy as well as any energy you’ve programmed. Crystals also attract negative energy, so you must regularly cleanse them to avoid unwanted effects. By keeping your crystals clean, they’ll only store their energy, your energy, and the programmed intention.
You can start with basic programming methods if you aren’t familiar with storing energy in crystals. For example, you can program a crystal by writing your intention on a piece of paper, placing it under your crystal, and leaving it in direct sunlight. The masculine energy of the sun can help with success and focus during your interview.
Additionally, if you have limiting beliefs or anxieties getting in your way, you can work with the energy of a full moon to dissolve them. Simply use the same technique as the sun but place the crystal and paper under a full moon. The energy of the full moon will help you release negativity.
