About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2558132460. Listed at 13 retailers as of November 1, 2026, with prices from $50,351 to $78,251, a $27,900 spread on the same certified stone. MOH London lists it at $78,251. 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.
