About this 3.01ct natural marquise diamond

This 3.01ct natural marquise sits in the three to five carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of November 5, 2026, with prices from $36,370 to $42,792, a $6,421 spread on the same certified stone. Blue Nile lists it at $42,792. 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.
