About this 5.5ct natural heart diamond

This 5.5ct 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 6552399708. Listed at 5 retailers as of November 2, 2026, with prices from £161,139 to £203,187, a £42,048 spread on the same certified stone. B2C Jewels lists it at £203,187. 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.
