The conversation concludes with Paul and Matthew discussing thoughts on lab-created diamonds and Matthew shares his findings on the subject while researching for an article he recently wrote for digital-weekly AIRMAIL titled “The Blingless Ring.” Next, Matthew explains how he approaches writing his books, what his technical and creative process is like and why likes to write about the diamond industry. Author Matthew Hart rejoins the show upon the debut of his latest thriller novel “Ice Angel.” The conversation begins with Matthew providing a glimpse into his new book (a follow up to “The Russian Pink”) which involves the murder of a diamond prospector in the Canadian North and a plot that parallels the current geopolitical climate between the U.S., Canada and China.
