About this 2.51ct natural emerald diamond

This 2.51ct natural emerald sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6531502074. Listed at 11 retailers as of October 28, 2026, with prices from $20,543 to $35,812, a $15,270 spread on the same certified stone. MOH London lists it at $35,812. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
