This example is opaque with a clean polished surface, and the ironstone backing provides natural stability and contrast rather than distracting inclusions. The dimensions and carat weight place it in a desirable size class for fine jewelry, and the absence of treatments enhances both aesthetic desirability and long term value for collectors who prioritize natural, untreated material.
