Every day people frequent diamond forums with a GIA Report and ask the experts what they think. The most popular dialogue is the consumer showing the stats on the GIA Report and folks giving their opinion based on the data provided. Is this sufficient? A popular online tool is the HCA (Holloway Cut Advisor) and if the diamond scores well (between 0.0 - 2.0) the diamond is generally recommended.

We compare in our critical optical analsys as well as practical observation alongside one of our GOG Signature H&A GIA Ex's to see the differences.
