This bright, highly polished gem calcite rhombohedron is water-clear, making it easy to see it perform the "magic" trick of double refraction. This Iceland spar is an unusually clear and highly aesthetic specimen of optical quality calcite. The rhombohedron is prismatic and water-clear, allowing total transparency through all the sides of the crystal, and top-to-vottom and side-to-side as well.  It measures 3.7" tip to tip, and 2.3" on the longest edge.
