Black obsidian is a powerful cleanser of psychic smog created within your aura, and is a strong psychic protection stone. It has powerful metaphysical properties that will shield you against negativity, and the energy of this stone may stimulate the gift of prophecy. Pieces of this stone were often used in the past for scrying. Obsidian draws out mental stress and tension. It stimulates growth on all levels. We do not use any filters or special lighting when taking images of our items. What you see is what you get. I have always said I wouldn’t use lighting or filters for my images, a simple camera to honestly capture these beauties... however... it does make these mirror like spheres rather troublesome. So please accept my apologies for the poor photos! FURTHER INFORMATION: - Macro photography is used to show detail but can make some items appear larger than their actual size. - Not one crystal is the same. They differ in shades and sizes. Please remember that crystals are naturally occurring.
