What is the HCA tool (Holloway Cut Adviser) and how relevant is an HCA score?

The Holloway Cut Adviser (HCA) is an easy to use online tool to help analyze the proportions of a round diamond from a cut quality perspective.  It is considered a "rejection" tool to identify/eliminate diamonds with problematic proportions.  The value of this tool was quite significant before the release of the AGS Light Performance grading system in 2005 and the GIA cut grading system in 2006.
  
The relevancy of the HCA tool is somewhat marginal today, but can still be useful in certain circumstances. To learn more, see our page on the HCA tool.
