About this 4.02ct natural cushion diamond

This 4.02ct natural cushion sits in the three to five carat band, graded FANCY YELLOW colour (tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1555066127. Listed at 5 retailers as of November 3, 2026, with prices from £10,943 to £20,701, a £9,758 spread on the same certified stone. MOH London lists it at £20,701. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
