In contrast to baguettes, coffin stones have a tapered shape.
Coffin stones are used typically in larger chandeliers where they take up significant amounts of space. They are usually with holes at the top and bottom resembling an old-time wooden coffin. The baguette is similar but doesn't taper. Coffin stones are frequently beveled to allow more light refraction. Most common are the 2 to 5 inch tall versions and usually have a flat back side.
