HEAT-TREATED/COMMON CITRINE is a very common form of Citrine. It is created by heating Amethyst crystals to a high temperature. Heating Amethyst crystals does not damage them, since crystals and minerals are formed from the high temperatures within the Earth. However, once Amethyst crystals are heated, they have a very different energy when compared with Natural Citrine. Common Citrine has a lighter energy, and helps to bring a vibrant Light energy into the aura. It can assist one in releasing heavy emotions or thoughts, and is also helpful in setting proper emotional boundaries so that goals can be more easily manifested and aligned with Divine Will. Chakras: Root, Sacral, Solar Plexus. Element: Fire. (Sizes: Extra Small 1/2 inch, Small 3/4 - 1 inch, Medium 1 - 1 1/2 inches, Large 1 1/2 - 2 inches)
