Carving crystals and gemstones is a tradition that dates back to ancient times. Carved crystals are believed to enhance energy, raise vibrations, and direct energy. Crystal towers, also known as, Standing Crystal Points, are often used as the center point of an alter or crystal grid, as they direct energy out of the terminated point amplifying your intentions. They are also often used to grid a room by placing them in the corners of the room to protect your space from negative energy and create a peaceful environment.
