Q: What is your process of re-cutting a diamond?
2 By the time we get the diamond onto the scanner, we already have a good idea of what the optimal shape would be. (We’ve learned that experience indicates, while technology confirms and expedites.) Within a minute, the scanner provides us with detailed measurements that would normally have taken hours to measure. Once the desired shape is confirmed, we proceed to re-profiling the diamond to get it perfectly round. Once the diamond profiling is complete, we measure it again and capture the updated parameters.
3 The next stage is for the faceting of the diamond’s pavilion (the lower half of the diamond). A modern brilliant shape has 24 pavilion facets. A high light performance diamond such as a Sirius Star® 80 has 48. If you take a closer look at the facet configuration of a modern brilliant diamond vs a Sirius Star® 80, you’ll understand the complexity of design, and the skill required to masterfully craft each of these facets.
4 Lastly, we come to the crown facets. Master Diamond Cutters have to perfectly align all the facets to achieve perfect symmetry (along with a variety of other critical factors). Throughout the entire production process, the diamond is scanned, measured and analyzed to ensure that the projected outcome is delivered. This quality control ensures that the symmetry and polish of each facet will contribute to the highest possible cut grade in the industry.
Before
1 Once we receive a diamond, we weigh it, measure it, and proceed to analyze it (including time under a microscope) to determine whether it is a natural or synthetic diamond, or has been treated for color or to remove impurities (inclusions). We also
determine whether there are any inherent flaws (twinning stress) that we need to consider during the re-cutting process.
