About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded H 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. Listed at 3 retailers as of October 31, 2026, with prices from $25,906 to $30,492, a $4,586 spread on the same certified stone. Blue Nile lists it at $30,492. 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.
