Natural pear diamonds whose GIA report records brown — a notation beside the colour letter, or a fancy grade where brown is the dominant colour. Every stone is read from its own GIA grading report. The comparison price on each card is what a similar near-colourless (G–H) diamond lists for, not a former price.
Step cuts show a champagne tint evenly, brilliants scatter it. Shape-by-shape counts and median prices from 2,822 stones at nine retailers.
