Optical Calcite Sphere point The sphere gives off aOptical calcite sphere with rainbows and layers facing every direction. Each measures 40 42 mm in diametere and are approximately 100 grams. For transparency: These were sold to me as gypsum selenite spheres, but they are harder than typical gypsum (2). A box knife, peridot (6. 5 7), lapis lazuli (5 6), apatite (5), and caribbean calcite (3 3. 5) scratch the sphere but malachite (3. 5 4), fluorite (4) and bladed barite (3 3. 5) do not scratch.
