About this 2.51ct natural emerald diamond

This 2.51ct natural emerald sits in the two to three carat band, graded E colour (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 5151742188. Listed at 5 retailers as of October 28, 2026, with prices from $42,326 to $53,510, a $11,183 spread on the same certified stone. 77 Diamonds lists it at $53,510. 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.
