About this 4.05ct natural oval diamond

This 4.05ct natural oval sits in the three to five carat band, graded J 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 6515945410. Listed at 23 retailers as of October 29, 2026, with prices from $43,312 to $71,454, a $28,143 spread on the same certified stone. MOH London lists it at $71,454. 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.
