About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 780668859. Listed at 5 retailers as of November 5, 2026, with prices from £1,417 to £3,456, a £2,039 spread on the same certified stone. NZ Jewellers lists it at £3,456. 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.
