Anatomy of a Diamond Blue Nile

Diamond Anatomy The graphic below explains the major parts of a diamond. When considering diamond anatomy, the three most important components are diameter, table, and depth. This is because the ratio of the table to the diameter, and the depth to diameter, figure prominently into determining a diamond's cut grade. While understanding a diamond's anatomy can be helpful, it

How to Choose an Oval Diamond Based on its Proportions ...

For diamonds greater than 0.75ct, our proportions result in diamonds that are about 3% bigger on average for the same carat weight. Note that the non-optimal average is inflated by the low-depth diamonds that leak light, so this difference is underestimated. An extra 3+% difference might not sound like much, but that’s worth a lot of money when you consider diamonds cost thousands of dollars.
