About this 6.55ct natural oval diamond

This 6.55ct natural oval sits in the over five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 7512855801. Listed at 3 retailers as of October 29, 2026, with prices from $321,520 to $390,644, a $69,124 spread on the same certified stone. 77 Diamonds lists it at $390,644. 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.
