Natural Fire Agate often looks brown when viewed indoors, but take it outside into the sunshine, and its true colors will be revealed! The "fire" shifts and moves as the light dances across the surface of the stone. The actual Agate has been polished, but it is still partially attached to the rough matrix stone. Fire Agate is highly recommended to take to the workplace, especially if your coworkers or customers have negative energy. Keep it on your desk to protect you from negative vibes so you can keep on shining bright!
