In addition to showing fine 3d structure and texture, this mineral is rather sparkly, the visual effect being the result of small (with a few large) specular highlights that are rivalrous. The retinal rivalry will distract some, but is essential to communicate the optical qualities of this material. Shot with the Panasonic Lumix 3D-1.
