About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded I 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 6555494651. Listed at 10 retailers as of October 31, 2026, with prices from HK$185,802 to HK$234,445, a HK$48,643 spread on the same certified stone. 77 Diamonds lists it at HK$234,445. 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.
