The beauty of Amethyst is evident whether the stone is in its natural state, cut or polished into jewels. It is the birthstone for Pisces and the February birthstone along with being the stone for the 6th anniversary of marriage.
Amethyst is my favorite variety of quartz crystals . And it is considered the most powerful and protective stone of all crystals .It has been sought after throughout the ages for its stunning colors and ability to stimulate the mind and emotions. It is also used to help remove bad habits.
