Study Notes
Diamond Grading and Concepts
- Diamonds can be repolished to improve clarity (VVS1 or VVS2 grade) or potentially to Internally Flawless grade.
- Recutting repairs damage or refashions a polished diamond improving clarity, proportions, or color, to modernize an older style cut.
- Repolishing refinishes a polished diamond to fix clarity or finish flaws.
Key Diamond Concepts
- A mounting often hides features of a diamond.
- A grader may use light reflections to discover inclusions hidden by prongs.
- Practice improves accurate weight estimation.
- Proportions (girdle thickness) affect weight estimation accuracy.
- Estimated weight estimations may vary from actual weights in certain cuts.
- The value of the finished diamond guides recutting decisions.
- Variations in cut (fancy cuts), may not appear in rounded diamonds.
- Diamonds are vulnerable to damage in jewelry.
- Modern cuts and old-style cuts are equally important today.
- Original cutting style influences the final recut style of a diamond.
- Market demand impacts recut shape choices.
