Which term describes a diamond with its table nearly parallel to a possible octahedral face?

• A. Three-point diamond
• B. Transmission
• C. Total depth percentage
• D. Trace elements

Answer: (A)

When a diamond’s table is nearly parallel to one of its octahedral crystal faces (the {111} planes), the crown facets align in a way that three distinct points or “points” become noticeable around the girdle when viewed from above. This orientation effect is what leads to the term three-point diamond. It specifically describes how the table’s angle relates to the crystal’s faces, not how light passes through the stone, how deep the diamond is, or what impurities are present. The other options describe aspects unrelated to the table’s orientation to the crystal faces.
