About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded D colour (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 6512438251. Listed at 7 retailers as of October 30, 2026, with prices from HK$252,796 to HK$319,164, a HK$66,368 spread on the same certified stone. 77 Diamonds lists it at HK$319,164. 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.
