David Craig Rotenberg was recently featured as an expert guest author on jewelry. His article “Man-Made Versus Natural Diamonds—How Can You Tell the Difference? And Why You Should Care” appears in The Aisle Wedding Directory, a wedding blog and vendor directory that provides couples with current wedding tips, inspiration and how-to information.

Natural Diamonds Prevail
David explains that while natural (taken from the earth) diamonds and man-made (mass-produced) diamonds share similar optical, chemical and physical characteristics, there’s a big difference between them, especially in terms of long-term value.

He says that shoppers should “never assume any diamond is a naturally mined diamond unless you have the reliable certification to prove it.”

David also explains that “while the FTC requires total specific disclosure language… to describe a man-made diamond, this specialized language was obviously lacking in enough cases that, in 2019, the FTC warned lab-grown diamond manufacturers against advertising these diamonds as “eco-friendly, “eco-conscious” or “sustainable,” since those terms “can be interpreted to imply certain specific environmental benefits” that can’t necessarily be substantiated.

More on the Subject
David first addressed the diamond origin controversy on our own website blog. He was recently quoted for his opinion on engagement ring trends and has also written for The Retail Jeweler magazine on the subject of gem carving appraisal.
