In 2014, I wrote that the lab-grown diamond industry was out-promoting the natural. That is even more pronounced now. I don’t get many pitches from natural diamond companies. And some of the pitches I do get are kind of dull. By contrast, I get at least two or three pitches on lab-grown diamonds a week. My Facebook feed is inundated with ads for lab-grown companies. The man-made segment claims only a single-digit percentage of the market, but it appears to be doing an outsized percentage of the marketing ... The fact is, the natural diamond industry made itself vulnerable to the threat of lab-growns. The industry didn’t promote its product for a decade. Everything that is happening now with lab-grown diamonds was predictable. The industry knew they were coming for decades. But the trade also failed to understand that the rest of the world wouldn’t see the two products the same way it does.
