Anatomy of a diamond

It is really useful when talking about diamonds to understand the anatomy of a diamond.

Having had GIA & GAA training I believe the information through the GIA to be very credible and accurate. Go to GIA Diamond Anatomy to learn more about the diamond:

  • Total depth
  • Table size
  • Crown angle
  • Crown height
  • Pavilion angle
  • Star length
  • Lower half length
  • Girdle thickness
  • Culet size

How to estimate a cut grade by the GIA is also very useful knowledge.

It is not necessary to have a full understanding of all this knowledge when buying a diamond as a diamond grader and expert will be able to give you advice. I’m a qualified diamond grader through the GAA so I would recommend making an appointment at Orsini Fine Jewellers in Parnell, Auckland. Ph 09 3543115 or email sarah@orsini.co.nz.
