Melissa first visited East Africa in 1998 and fell in love with Tanzania & Kenya on that trip. In 2018 she returned, traveling with the founders of Gem Legacy to visit gem mines and meet the miners. This offered Melissa a fresh and holistic perspective on the gems often used in the designs she sold. It was during that trip that she saw the positive impact the industry could have in these communities, and she felt compelled to join the effort to make gem supply chains safer, healthier, and more equitable.

Ginger Dery

Ginger Dery, Vice President of Roger Dery Gem Design, was a lover of color and fashion in the world of custom clothing and cosmetics, long before her foray into the world of gemstones began.

Bjorn & Rachel (Dery) Merisheki

This husband-wife duo is a Tanzanian 2nd generation Tanzanite miner and an American 2nd generation colored gemstone wholesaler who share a passion for supporting the base level of the human pyramid that is the colored gemstone supply chain.


They split their time between the two continents: while in the US they operate their wholesale colored gemstone business and fundraise for Gem Legacy, while in Tanzania they manage Bjorn’s family Tanzanite mine and operate Gem Legacy initiatives on the ground.


When they’re not visiting mines, they’re probably planning their next vacation or eating Indian or Lebanese food.
