Everyone is entitled to an opinion, even the uninformed.
There are many many people in the jewelry, diamond & appraisal business that have many years of experience and sometimes generations in the business that have no idea what an Ideal cut diamond is, much less a superideal cut. I worked for a man not long ago that was a 4th generation diamond wholesale dealer. I was helping him with his GIA diamond course and his AGS Way course. When he started learning about how to grade for Ideal cut, he could not believe what was involved. He had no idea.
You have to remember that most people in the jewelry business still do not have computers and have never been on the internet. If you ask most jewelers about a H&A diamond, 8*, A Cut Above brand, superideal cut, Ideal-Scope and the list goes on, they will give you a blank stare. These people are happy with thier 9-5 day and think they know everything about thier end of the business. Do they read and study to keep up...no. They have years of experience, which they think is enough. Sad!
