About this 5.12ct natural oval diamond

This 5.12ct natural oval 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 2235240539. Listed at 15 retailers as of October 29, 2026, with prices from $296,389 to $483,588, a $187,199 spread on the same certified stone. MOH London lists it at $483,588. 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.
