There are about 175 professional gem cutters working in the United States right now. Of those, between 30 and 35 have made rare, periodic excursions out of the country to source the rough stones they work with. Most meet with gem brokers at industry trade shows.

Roger Dery takes a more hands-on approach, putting his relationship with the miners as the utmost priority. To date, he’s made 30 trips to Africa, 6 to Sri Lanka, 3 to Thailand and 2 to South America. This willingness to go directly to the source eliminates the need to deal with multiple middle-men, streamlining the process to securing truly spectacular gems.

The mines are dark, hot, and potentially dangerous. The miners work long hours using the most primitive of tools. It’s not unusual for a crew to work for years without finding any significant gems. With only the presence of indicator minerals to guide them, the miners delve deeper and deeper into the earth in search of beauty.

Spending time with the miners, in the communities where they live with their families, is extremely important to us. Prolonged periods of political upheaval and conflict have had a devastating impact on regional economies. Directly sourcing gemstones where they’re produced helps build the local economy and enables parents to send their children to school.

Many of the people we’ve met have become our dear friends. Working with them isn’t abstract altruism: it’s our way to honor their wisdom, knowledge and dedication. Every time we’re able to spend time with them we come away strengthened in our resolve that individually sourcing rough gemstones for our clientele is the absolute right way to do business.
