This is a rather amazing, elongated calcite rhomb over 16 cm long! That is over 6 inches, folks! Not only do you have a crystal habit that is unusual for India, but the luster is excellent and the crystals range from translucent to clear. MOREOVER, there are flashes of color iridescence, on the surface (micro-inclusions of oil, maybe?). There is one contact point along the side, which has little impact on the visual beauty of this specimen, and it is fully and completely 360-degree terminated atop. The quality of the crystal actually enhances the honey-brown color, making this an aesthetic, unusual, and important specimen.
