About this 5.12ct natural oval diamond

This 5.12ct natural oval sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5241030710. Listed at 12 retailers as of October 29, 2026, with prices from $286,919 to $459,800, a $172,881 spread on the same certified stone. MOH London lists it at $459,800. 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.
