Synthetic CVD Diamonds
The past decade has seen remarkable breakthroughs in diamond synthesis using the chemical vapor deposition (CVD) method. These advances have lowered the cost of gem-quality laboratory-grown diamonds and deepened our understanding of diamond properties. This presentation will review notable milestones in CVD laboratory-grown diamonds and examine their broad range of industrial applications.

CEO And Founder
Menahem Sevdermish is the founder of the GWLAB gemological institute, formerly known as GIPS, and a leading expert in gem color analysis. Sevdermish is the author of the two-volume Dealer’s Book of Gems and Diamonds, comprising more than 1,000 pages, as well as many articles in respected gemological publications. Since 2003, Sevdermish has been engaged in the development of Gemewizard, the revolutionary digital gem-color communication and analysis technology used today by leading institutes around the world.
DR. DANIEL TWITCHEN
Sales Director for Chemical Vapor Deposition
Dr. Daniel Twitchen is the sales director for CVD synthetic diamonds at Element Six (E6). He has more than 20 years of research and development experience in synthetic diamond synthesis technology. An inventor or co-inventor on more than 50 patents, he has authored and co-authored more than 150 scientific publications. Twitchen helped establish E6’s diamond manufacturing in the U.S. His areas of focus include developing technology for growing synthetic CVD diamonds with tailored properties for applications ranging from thermal management for semiconductor devices to optics for high-power lasers. He and his colleagues’ work led to the development of a range of industrial Single Crystal CVD grades that were commercialized for mechanical, optical and electronic applications. His academic research interests now include using magnetic resonance and optical techniques to study how defects in diamond affect properties such as color and electrical conductivity. Twitchen received his master’s and doctorate degrees in physics from the University of Oxford. While there he was awarded the Harmsworth Senior Scholarship at Merton College for his doctoral studies. Following his PhD, he held a junior research fellowship, and was awarded the Engineering and Physical Sciences Research Council’s Advanced Fellowship at Oxford. He was also an invited academic to the Siberian Academy of Sciences.
