About this 6.4ct natural emerald diamond

This 6.4ct natural emerald sits in the over five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5202691514. Listed at 10 retailers as of October 28, 2026, with prices from £89,067 to £161,421, a £72,354 spread on the same certified stone. MOH London lists it at £161,421. 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.
