About this 5.18ct natural emerald diamond

This 5.18ct 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 6234356753. Listed at 7 retailers as of October 28, 2026, with prices from €102,989 to €186,924, a €83,935 spread on the same certified stone. MOH London lists it at €186,924. 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.
