About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2454259810. Listed at 17 retailers as of November 4, 2026, with prices from £3,356 to £6,241, a £2,885 spread on the same certified stone. MOH London lists it at £6,241. 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.
