According to Martin Rapaport inexpensive diamonds will be very sensitive to price increases. Noting that the cheapest goods might even show some improvement as buyers shift to the lower price points. He went on to say that you’ll see the bigger diamonds, where people just don’t care about the prices. If the prices increase, they’re going to want to buy more of them in an inflationary environment. So we’re looking at interesting market scenarios here. We’re looking at changes. We’re looking at a bifurcation or separation of markets.
