About this 4.05ct natural radiant diamond

This 4.05ct natural radiant sits in the three to five 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 2235973280. Listed at 13 retailers as of October 31, 2026, with prices from $87,522 to $152,137, a $64,616 spread on the same certified stone. MOH London lists it at $152,137. 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.
