Roger Dery Gem Design

Hi everyone! We have a new website, but choose to keep this one active for a while. As there are many links out there we would like to keep active. Can see our new work here:


Roger Dery…professional gem cutter, precision faceter and avid world traveler.

Roger’s passion is precision faceting the gems he travels worldwide to collect. Roger’s 34 years of experience in the colored gemstone industry have given him a zeal for attention to detail, unique designs and gems that come alive with their own story.

Roger’s gems and his signature designs based on his faceting and the gem’s own story are being passed down through the generations as they commemorate special occasions and memories, and mark rites of passage.

Roger’s enthusiasm for creating these fiery rocks comes from the enjoyment he receives from giving each of them a special home with people who appreciate them. We hope you enjoy viewing his work as much as he enjoys creating the gems.

Roger won a prestigious second place in the 2012 American Gem Trade Association “Cutting Edge” Competition with this Tanzanian Merelani Mint Garnet 8.77ct in a combination brilliant and step cut trillion design.

Roger has also been recognized for his works of service with his wife Ginger in a mining region of Tanzania. You can read about their work and the mining families here:
