Dr. Chuck Lein, president of Stuller, loves to talk about his company’s first Diamond Trading Company sight. After Lein and his comrades completed the DTC’s famously arduous applications, endured rejection on their first attempt, and received the nod on their second, they finally entered the DTC’s imposing headquarters in London as a full-blown sightholder last year. “There was always this curiosity about what happens in London,” Lein tells JCK. “We are ushered into this little room to get our sight. We were just like kids in a candy store. I didn’t know if they’d come out with a wheelbarrow or a big huge box. And a gentleman comes in with a plastic box that’s like what a kid packs his milk in. And he takes out just these two little poly bags full of diamonds. Two little sandwich bags. And I said, 'That’s it?’” That’s the diamond industry for you, Dr. Lein.
