Which statement correctly defines CLIPPIR Diamonds?

• A. Clarified Pearl Diamond properties.
• B. A type of diamond substitute from cubic zirconia.
• C. A rock formation in which diamonds are found.
• D. Cullinan-like, Large, Inclusion-Poor, Pure, Irregular, and Resorbed diamond.

Answer: (D)

CLIPPIR Diamonds describe a specific rough-diamond quality category used by gemologists to flag stones with exceptional potential before cutting. The acronym stands for Cullinan-like, Large, Inclusion-Poor, Pure, Irregular, and Resorbed. Cullinan-like points to a very high-quality benchmark similar to the famous Cullinan diamond, signaling outstanding size and overall premium potential. Large indicates substantial rough weight, which often translates to the possibility of a very large finished gem. Inclusion-Poor means the stone has few internal flaws, a crucial factor for achieving high clarity after cutting and maximizing yield. Pure reflects high chemical purity with minimal impurities that could affect color or clarity. Irregular describes a crystal shape that isn’t perfectly symmetrical, yet still holds strong value as a promising rough for turning into a remarkable polished diamond. Resorbed refers to surface features from partial dissolution during growth, a recognized trait that can appear on natural diamonds and still be compatible with high-quality outcomes. Taken together, this exact combination of attributes is what defines CLIPPIR diamonds. Other descriptions either refer to unrelated concepts (such as a diamond substitute or a rock formation) or to terms that do not capture the specific, recognized characteristics of this classification.
