About this 5.03ct natural heart diamond

This 5.03ct natural heart sits in the over 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 1236906679. Listed at 18 retailers as of October 30, 2026, with prices from $243,756 to $394,091, a $150,335 spread on the same certified stone. MOH London lists it at $394,091. 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.
