John Dyer, the first person to win an entire category at the AGTA Cutting Edge Awards (2005)
What is the difference between a good cut and a bad one? A gemstone should sparkle. Only a good cut makes a colored stone a gem. Many gemstones sparkle only on the outer edge with a dead zone in the middle. This is known as a window cut or a fisheye cut.

John Dyer is a world-renowned gem cutter. Since 2002, he has won 58 American Gem Trade Association (AGTA) cutting awards, taking a total of 14 first place awards. He is the only gem cutter to have won all the awards in one AGTA category three times (2005, 2007, and 2015). It is hard to believe that this master is essentially self-taught. When he and his brother David decided to start a gemstone business in 1996, they started the business with a trip to Zambia to bring back emeralds and aquamarines to be cut.

The cutter charged a high price for the job and did such a poor job that two of the three emeralds he cut had to be recut because they were unsellable. So John decided to take matters into his own hands, buying his first cutting machine. Through trial and error, he perfected his skills and pored over books on gemstone cutting until beautiful, sparkling gemstones began to emerge from his cutting wheel.
