About this 2.78ct natural heart diamond

This 2.78ct natural heart sits in the two to three carat band, graded I 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 6522372660. Listed at 22 retailers as of October 29, 2026, with prices from $28,402 to $52,534, a $24,132 spread on the same certified stone. MOH London lists it at $52,534. 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.
