About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1545341717. Listed at 8 retailers as of November 4, 2026, with prices from $11,262 to $18,005, a $6,743 spread on the same certified stone. MOH London lists it at $18,005. 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.
