What does the charts mean?

In order to simplify this chart, we have briefly explained the terms listed above.

  1. The carat weight is determined based on how heavy the diamond weighs
  2. The color is determined by how much yellow is in the diamond. The whiter the stone, the higher the letter. D is the industry’s most white stones. We only source loose diamonds that range between D – I color.
  3. The clarity is determined based on how internally clean the diamond is. The more inclusions, clouds, piques, and feathers that are found within the diamond, the lower it will be ranked. We only source loose diamonds that do not have any visible inclusions to the naked eye (S12 and higher).
  4. The GIA number. All of these diamonds have been sent to GIA and have received a report number. The complete certification is available at GIA’s website. You can copy the report number and insert it at www.gia.edu/report-check-landing to view the complete report.
  5. The diamond measurements. The measurements are the minimum diameter – maximum diameter x depth.
  6. The percentages of the depth of the diamond.
  7. The percentages of the table of the diamond.
  8. The size of the girdle. The girdle is the section that lies between the pavilion and the crown.
  9. The size of the culet. In modern stones, the diamonds don’t really have culets, but in antique diamonds, the culets typically range from medium to very large. The culet is one of the most distinguishing elements of an antique diamond.
