About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded G 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 5556471918. Listed at 6 retailers as of November 1, 2026, with prices from HK$118,241 to HK$183,806, a HK$65,565 spread on the same certified stone. MOH London lists it at HK$183,806. 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.
