About this 3.21ct natural heart diamond

This 3.21ct natural heart sits in the three to five carat band, graded D colour (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 7548281294. Listed at 22 retailers as of November 4, 2026, with prices from HK$388,518 to HK$751,300, a HK$362,783 spread on the same certified stone. MOH London lists it at HK$751,300. 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.
