In 2012, Donald Clark retired and passed along stewardship of the IGS to Seth and Lisa Rosen. Seth and Lisa were longtime members of the IGS. Seth is a gem collector and active Internet entrepreneur, who had already spent a great deal of time in the custom jewelry business. He founded <a href="https://www.custommade.com/">CustomMade, the world’s largest online custom jeweler</a> and also operates <a href="https://www.ganoksin.com/">The Ganoksin Project, a technical resource website for bench jewelers and jewelry manufacturers</a>. Seth and Lisa felt strongly that the IGS needed to remain a cost-effective, accurate, and comprehensive resource for all those interested in gemology. IGS is our passion, and it is a family business.
