About this 3.51ct natural marquise diamond

This 3.51ct natural marquise sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2235856296. Listed at 14 retailers as of November 4, 2026, with prices from HK$623,576 to HK$905,022, a HK$281,447 spread on the same certified stone. Frank Darling lists it at HK$905,022. 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.
