About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1505428687. Listed at 9 retailers as of November 2, 2026, with prices from HK$170,092 to HK$286,119, a HK$116,027 spread on the same certified stone. MOH London lists it at HK$286,119. 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.
