The Roger Dery Gem Collection is home to the top 1% of colored gemstones in quality, precision faceting, and attention to detail in each gem’s sourcing.
Our family shares a second-generation passion of over 40 years: sourcing gems unconventionally, one by one, to create a collection of hand-picked treasures, and a distinctive and artistic approach to the gemstone faceting process that channels the gem’s potential.
We purchase gems in the source country whenever possible because we are committed to building relationships with miners to understand their challenges, support their community, and encourage the success of their families.
Our standard diamond powder for polishing is 4 times finer than the international standard because our goal is to maximize 100% of every gem’s beauty.
We take an artistic approach to design by taking into account each gem’s individual characteristic and creating a design that is uniquely curated to maximize its beauty.
Use our Color Search to discover new gems in your favorite color and discover new colors of your favorite gems.
We donate a portion of every gem purchased to Gem Legacy, the 501(c)3 nonprofit philanthropic partner of Roger Dery Gem Design.
Gem Legacy supports vocational training, entrepreneurship, and community development in East African artisanal mining communities.
Our commitment to precision in faceting while curating our faceting approach to the individual gem’s characteristics optimizes the gem’s beauty to maximum potential. Vividly displayed in this Blue Sapphire is the difference between faceting for maximum weight retention versus maximum beauty potential.
