Agate Crystal Point Obelisk
Agate protects you emotionally and brings harmony. This may be helpful, especially if you are one to have a fluctuation of emotions. Each color of agate, in itself, has a separate power and meaning, but harmony and protection are a common theme in each color. Some agate stones mimic a talisman worn to ward off the evil eye, so that is definitely an option for a natural protection against negativity.
Each stone is roughly between 110-130 mm!
