About this 4.2ct natural emerald diamond

This 4.2ct natural emerald sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5232521865. Listed at 5 retailers as of October 29, 2026, with prices from £50,491 to £79,118, a £28,627 spread on the same certified stone. MOH London lists it at £79,118. 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.
