About this 2.51ct natural emerald diamond

This 2.51ct natural emerald sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6535744063. Listed at 21 retailers as of October 29, 2026, with prices from $27,150 to $48,184, a $21,034 spread on the same certified stone. MOH London lists it at $48,184. 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.
