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 VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6205944203. Listed at 2 retailers as of November 6, 2026, with prices from $11,690 to $13,778, a $2,088 spread on the same certified stone. B2C Jewels lists it at $13,778. 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.
