It is great to be able to see the natural surface of rough Labradorite while still having a full side that is polished to perfection so that you can see the wonderful ""flash"" that makes labradorite such a prized stone. Labradorite is a crystalline form of Feldspar, often gray in composition but known for its ""flash"" or ""flame"" when it catches the light. When polished, dark gray Labradorite flashes with colors deep within, including blue, green and gold. Highly mystical, Labradorite heightens intuition and enhances psychic abilities, making it great for working with the Third Eye Chakra. Intuition and intellect are balanced by Labradorite, illusions are dispelled and true intentions are seen more easily with its use. Labradorite is also very protective against negative energies, balancing and protecting the aura and sealing the aura from energy leaks."
