Fractured Quartz Above. Regrowth on a natural fracture near the termination of a large quartz crystal. Ron Coleman mine, near Jessieville, Garland County, AR Below. Rehealing of a "splinter" fragment derived by natural breakage of a large quartz crystal by earth movement. Specimen from Ron Coleman mine, Jessieville, Garland County, AR. Notice the rainbow colors. Faulted crystals are a little different than fractured crystals. Many crystals get fractured and reheal so the fracturing does not reach the surface of the crystal. This is one way "rainbow" reflections are generated, see the above photo. Faulting of a crystal actually offsets the two or more pieces, therefore the two parts might still be adhering to each other due to later growth, like in the photo on the left, or might be recovered as two separate partial crystals, sometimes with regrowth on the broken portion of each piece.     Next page is inclusions in crystal.
