Each figure is the median asking price of that shape’s live listings — not a like-for-like comparison between shapes. Cut grade is the biggest single driver of a diamond’s price, and our retailers don’t publish it, so we won’t tell you one shape is cheaper than another when we can’t hold cut constant.
