The matrix of this specimen has a large vein of colemanite and celestite running through it. On one side, there is a cavity filled with crystals of these minerals to 0.7" (1.8cm). The matrix of this specimen is composed of many tiny crystals of what appears to be celestite. The matrix fluoresces pale yellow. Several crystals on the edges of the cavity are broken; overall, though, most are intact.
