We’ll be frank darling. The diamond industry benefits from confused customers. From the low-rent retailers to the high-end boutiques, the lack of clarity is positively appalling. High-quality diamonds with scandalous mark-ups, low-quality diamonds with scandalous mark-ups; an industry that buys and sells carat and clarity this opaque? You can almost smell the irony. And online retailers? All that can really be said is…good luck.
