About this 6.37ct natural oval diamond

This 6.37ct natural oval sits in the over five carat band, graded H colour (near-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 2231356035. Listed at 18 retailers as of October 27, 2026, with a 43% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
