About this 3.12ct natural cushion diamond

This 3.12ct natural cushion sits in the three to five carat band, graded I 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 6137018968. Listed at 6 retailers as of November 4, 2026, with prices from £22,467 to £28,070, a £5,603 spread on the same certified stone. 77 Diamonds lists it at £28,070. 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.
