The Materialist : Rob Bates

This episode of The Materialist is a little different.

Usually, we talk with designers, tastemakers, collectors, and creators about the objects they love: the jewelry they wear, the pieces they make, the things they choose to bring into their lives. This conversation is about jewelry, but it is not really about looking at jewelry. In fact, Rob Bates says at one point, “I don’t really like looking at jewelry. It has no interest to me. And I’ve written about jewelry for 35 years.”

A diamond is never just a diamond. It is a product, a symbol, a commodity, a brand, a promise, a controversy, a livelihood, and sometimes a problem. The same object can represent romance in one context, extraction in another, national development in another, and market disruption in yet another.

Much of the conversation circles around lab-grown diamonds, which Rob identifies as the biggest issue facing the industry today. His analysis is characteristically unsentimental: lab-grown diamonds succeeded not because they invented a radically new use case, but because they inserted themselves into an existing emotional and commercial structure. The mined diamond industry had spent decades building demand. Lab-grown companies arrived and said, in effect: this is the same thing, only chea
