Are lab-grown diamonds really that much more expensive than lab-grown corundum? But lab-grown is apples and oranges; I’m talking about real stones.
It seems like most of the money is going into the cut either way, and the resale value (especially if you’re going through a fence) is going to knock at least a digit off whatever you manage to steal. The first thing I thought when I saw the 5.7M headline was, “Pssh, that’s retail.” You’re not going to get a grand for a 1-2 carat stone if you’re not a retailer marking it up.
