The above diamonds have proportions and angles which are required for AGS’ ideal cut grade. The American Gem Society (AGS) has developed a diamond grading system which is based on light performance. This is by far the most effective way of determining the cut quality of a diamond as the system takes into account the very advanced research conducted by both AGS and its sister organization GIA. See The Fascinating Science of Diamond Fire.

The Brian Gavin diamond is a certified AGS 0 diamond as it has a grading report issued by AGS. In addition it is grown by Clarity Diamond in Austin, TX, USA, using a unique process (patent-pending) allowing for better transparency in the material.

The Selection Process

I assess diamonds for a number of factors. For a diamond to be included in my recommendations it must have:

  • The required angles according to potentially qualify for AGS’ ideal cut grade;
  • good contrast
  • optical precision
  • high quality diamond material;
  • good value;
  • no visible inclusions (eye-clean);

I only include a diamond I am confident the recipient will absolutely love.

The selection process involves (though is not limited to) keeping the search parameters within the ones I have published here:

Also worth reading to help understand my process and to know if and when the above parameters can be expanded, and what the consequences are:
