About this 1ct natural emerald diamond

This 1ct 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 766663508. Listed at 14 retailers as of November 4, 2026, with prices from £1,056 to £2,791, a £1,736 spread on the same certified stone. NZ Jewellers lists it at £2,791. 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.
