A large scolecite crystal grows into a fan-shaped pattern.
A large scolecite piece is seen up close in a black display case. The scolecite sprays are lit above the center of the piece, making it difficult to see the sides of the wide spray piece. The crystal has grown into a wide fan shape with hundreds of tiny to large cylindrical points. The largest is in the center back, while the tiny pieces are along the outside edges, as seen at the bottom. The points on the growths are almost blunt, and some are nearly flat. The crystal growths have a unique shape along the top, with a section of medium-length points on the left and a section of short points between the center and left. The right side points are almost as long as the center point, with a dip in length between the right and center. The points have a high transparency, and the larger points show the black background through the stone. While the lower section with numerous points crowded together is almost solid white with gray variations from the shapes of the growths. A small, rough gray stone is seen at the bottom of the points where the crystals have grown. The bottom of the image shows a partial reflection of the crystal piece, while the remainder of the surrounds and background are completely black.
