About this 5.09ct natural emerald diamond

This 5.09ct natural emerald sits in the over five 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 5234057990. Listed at 5 retailers as of October 29, 2026, with prices from $203,166 to $333,305, a $130,139 spread on the same certified stone. MOH London lists it at $333,305. 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.
