About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 823631635. Listed at 9 retailers as of October 30, 2026, with prices from £1,389 to £3,863, a £2,474 spread on the same certified stone. NZ Jewellers lists it at £3,863. 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.
