About this 3.12ct natural cushion diamond

This 3.12ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 3555511497. Listed at 9 retailers as of October 28, 2026, with prices from £12,990 to £16,915, a £3,925 spread on the same certified stone. GemTrove lists it at £16,915. 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.
